Morrisons review: Food to order

I ordered food for my three years old birthday party on the 9th October for a 12-13.00 pick at the stirling store on November the 3rd. However, I arrived at the store and was told after a wait that the order was cancelled. I had not cancelled the order so

Must be due to an error within Morrisons online system. I had paid a £20 deposit on the 9th of October. We were then told there would be a half hour wait before the order could be made up again. Unfortunately my daughter had a tummy bug and we were having to run back and forth to the toilets. We waited 45 minutes and went back to the kiosk where we were told quite abruptly at customers services to wait in the queue behind the kiosk which was ten people long, after waiting an hour this was not great. During this time my daughter had an accident and we had to leave the store, there was no one around apart from one person at the kiosk who had both jobs to do to tell so I told this member of staff and we left. My daughter was in some distress by the time we got home and we ended up cancelling her party and she had no food for this in the end anyway. I am complaining in order to raise your awareness to the error in your ordering system which is being passed through to the Stirling store, probably also to highlight the short staffing issues at the kiosk/customer services area and for request my £20 deposit to be returned as soon as possible. We are grateful for the help we did receive in arranging for the order to be made up but we were unable to wait any longer. I would appreciate a speedy response and return of my deposit and also a look into your systems as to why my order was cancelled. Thank you.
