Bad service

<p> Last week I was at KFC and placed an order at the drive through. I gave the lady a R100 in cash and told her to deduct the balance from my debit card. After the transaction was completed I collected my order at the second window. The lady gave my order but without the cooldrink. I called her and told her I'm waiting for my drink. She rep**** and said that the lady at the first window must give my cooldrink. After going back and forth I finally got my cooldrink and left. When I got home I've notIced that they gave me a boxmaster with a regular fillet, not as I requested a zinger fillet. Then this weekend while checking my bank statement, I noticed that they deducted R100 from my bank account, So all together they charge me R200 (R100 cash and R100 from my bank account) for a order that was less than R150. I dont have a slip as the lady at the second window took the slip. So, what do you do in a case like this?</p> <p> </p> <p>This is only one of plenty bad incidents that I've experienced when going to KFC Soneike. Never going there again</p>
