KFC Harassment of customers

Last night the 05th of March 2019 my husband and I ordered Kfc from the Pinecrest Branch in Pinetown. 1stly - Lady couldn't understand me but that was fine, we all have long days. 2ndly - she captured my payment via card wrong (I wasn't aware because I just put my pin in and there was no amount showing on the Nedbank card machine, as I gave the slip to my husband, we didn't check thinking it was correct). 3rdly - We get home and my order of a 6 piece chicken box was not in my bag. I phoned the branch and they took my cell number and arranged for delivery from the Nanado's guys. 4thly - The whole day the 06th of March 2019 I have been getting calls from the KFC staff members from their cellphones that I need to come into the store and pay the additional amount because they made a mistake when they put the purchase amount into the card machine.

I called KFC customer care line on the 06th of March 2019 querying this as I was asked for my bank statement, last time I checked I was not applying for an account by KFC. Also the fact is, how does KFC get a hold of the millions of clients where the wrong amount was entered and get those client details so that the clients can pay the additional fee?

Had I been called and nicely spoken too and explained the situation, I would have no problem paying the additional fee. This is harassment as the KFC staff keep phoning my private cell number off different cellphone numbers and not from the store phone number or from the head office.

I strongly recommend that you do not order from this branch as they clearly can not understand when enough is enough or that mistakes can happen and warnings are real in the working industry. Should I continually be harassed , I will be getting my lawyer involved.
