Absolutely terrible Service

Last night we went to KFC Vereeniging general hertzog en every time we give them the benefit of the doubt, but last night once again there was a problem, we order the 5 zinger strips, double crunch burger meal, once small chips and 6 zinger wings, we asked the lady at drive thru we don't want any ice in our coke, just to find out at home there was ice in, but besides that, the cashier confirm that everything was in our packet, when we stopped to check my zinger strips was not in our bag, when my husband went back and told the lady that the other cashier confirmed everything was there her words "oh she did not check" excuse me but is it not your job to check if the order is correct, they could not even apologize for the mistake, when we got home which was about 2 mins drive, my zinger strips as well as my husband zinger wings was cold, that was not very appetizing, once a week we buy KFC at the same place and not once was our order correct we have to drive back every time for something that is missing from our order, I mean come on is this the best service you can give your clients.
