WORST CUSTOMER SERVICE - Will not shop here again!

Despite a well-stocked wide variety of fresh products in this local convenience store, the customer service and management of the store are SORELY lacking. I'd disappointed at how I was treated. Went to order platters at the deli on Sunday ahead of my child's birthday party. Was not given a receipt and told I could pay on collection. My mother called midweek to adjust the order and was told nothing would be made until payment was made and she had 1 day to pay in full. She was told this policy was due to prior past experience when customers didn't pay. Whilst I understand that no one told me this when we were in the store and I work quite a distance away from the store so this is a MASSIVE INCONVENIENCE to come all the way back just to pay. when I called the store manager to complain and air my frustration I was told "We apologize for the inconvenience but you must pay in full and I'll see what I can do" I asked for the invoice to be emailed to me so that I could EFT and was hoping for some sort of compensation but nothing. Nothing to make up for the inconvenience. I've been in a customer service role for 23 years and I have never spoken to someone the way that manager spoke to me. He was not helpful and simply saying "sorry" or "apologies" does NOT rectify the matter. He also said he's done what he can. Well, he didn't he could've discounted my order. I canceled my order and won't do business with that SPAR again. bad bad customer service skills...what a horrible experience...no empathy...If my mom didn't call the store we would have had NO PLATTERS made for my sons first bday :-(
