Over Debited and No Response after 36h

I was happy with King Price for some months; however, I changed my policy after they sent me a terrible price increase on my new year.

The company failed to make the change on the system, and still debited the original price from the changed policy. I have now been over debited by over R600. I contacted them to ask that they reimburse me as soon as possible. I was told that someone would call me. No one called. I contacted them again later in the afternoon, and they told me that someone can only attend to my issue in 24-48h. This is at 5pm on a Friday.

There seems to be very little concern for a major error that was made on the side of the company. This effects people who have tight budgets.

I am very disappointed in this error and response from King Price.
