Poor of the poorest service in multichoise

I was debited the incorrect amount of R399 instead of R105. Before this has happened, I received an sms notification that R399 is due to my account. I then called the poor customer service center to query about the sms I got. The lady by the name of shoela Mabatla told me that she wil cancel the debit and I will be debited the correct amount of R105 but that didn't happen. I can't again yesterday on the 26th querying about the incorrect debit and I then requested a refund that has not happened to date. Today the 27th June I called again and I was told that someone from finance will call me even now I. Still waiting. This has cost me a lot of problems due to my other debit orders and I want this matter to be taken serious as for us clients of multichoise we not take care of.
