Service, food, drive thru times

So since my last hello Peter or complaint about KFC soneike I have given them time to improve but that hasn't happened. I have visited the store at least 6 times, 3 times in store and 3 drive thru. Even the store manager Cindy has a attitude and said I should go ahead and hello Peter. Drive thru times are pathetic, the store marks off orders from their orders boards just to give them a perfect delivery time when the order has not even been received by the customer, I waited about 20 minutes for my order in store due to the delay of the staff which I still have not received a answer as to why there was a delay even upon questioning the store manager she could not answer, the attitude of the staff is pathetic to say the least, I cannot leave the store without checking my order in case I get home and something is wrong cause that is the norm, when you go threw the drive thru you first wait about 5 minutes at the last window before you get greeted by grumpy staff members who has no understanding of the word customer service, I always loose my appetite when going to store and the food I must always complain about because something is not right or fresh. When will things change for the better? Even the store manager has a attitude and I would like this complaint to be escalated to the area manager.
