AutoZone

I went into autozone not exactly sure of my available balance on my debit card but was hopeful I could afford the repairs necessary to get my singular mode of transportation operable and back to a road worthy state. After gathering all the items I felt where necessary to give the vehicle the necessary maintenance needed I approach the counter... Recognizing faces from prior dealings and explained that I was uncertain is I would have enough available to purchase all the items I wished but they said well well find out n no big deal... I was asked to swipe my card and was declined then I was told that they had been having problems with this registers card reader and requested I try again which I did with the same result then to be asked to insert it once more but to request it be run as credit when given the option which I did... At which point I was told I only had 245.40 available on my card... At which point I told the familar faces that guess id have to skip the oil change and air filter replacement until the following week and they gladly removed the related items from my intended assortment of purchase which after reringing up came to a total far below my previously expressed available balance... Roughly 220 dollars so I then proceeded to insert my card once again only to be declined at least three more times on following attempts... I and person running the register where puzzled but before I held up the normal flow of transactions that where waiting to be made I simply asked that my items be set aside momentarily while went to the nearest atm to retrieve the cash and id return shortly only to be declined at the atm and then the restaurant following that... I assumed that the multiple card trying at autozone may have triggered a fraud protection lock to be placed on my card so I humbly just went home hungry n a lil irritated only to call the bank the following day to request the hold/lock on my card be removed at which point I was informed that there was no such lock placed on my card and that the reason it didn't work was because i'd exhausted my available balance... I then ask why only to be told that my purchase of 245.40 at autozone had brought my balance to 0.00 the night before. I then called rather irritated to speak with the manager about the fraudulent charge on my account seeing as how I never was able to complete a purchase and left the store empty handed... And was now irritated and famished only to be told on friday that she (the manager) (christina) at the pryor, oklahoma store hadn't eaten since tuesday and that she didn't know what to tell me. At this point after asking if I truly was speaking to a manager asked if I could have a number for corporate or regional management and told her i'd express the fact that she was starving to them. I called the number given shortly before noon on a friday only to reach an automated answering service requesting I call during normal business hours... So I selected to leave a message in which I explained my grievance and requested a call back and iterated my name and contact information at least three or more times... Before noon on what I expect is a normal business day never to hear a word back now it's sunday and i'm still completely broke and hungry with absolutely zero money... I went to the store to express my sincerely desperate need for this to be resolved and to show the manager which register it took place at only for her to call the police on me and express that I had been hostile... Smh.. However frustrated I had and have become I never made any threats towards her I simply said that I agreed that she did look hungry... Referencing her comment about not eating since tuesday which would have been three days prior... Anyhow i'm still broke n starving with nothing to eat or parts to complete the repair I set out to complete n will be walking with nothing to eat several miles to work passing the pryor oklahoma autozone that I feel has robbed and starved me... What can I do to get my money back?
