***** and no feedback

On 9 Nov, I rec an sms on my phone saying I had drawn R1400 from my Standard Bank credit card from Pineslopes area. I phoned ***** dept immediately as I was at work in Bedfordview and received a case number & cancelled the credit card. 2 days later another R1000 was taken from Blairgowrie off the 'NEW' credit card which had NOT been printed yet or left the bank. Makes one think it's an 'inside' job! I went into the Bank & found they had also taken R2000 out my cheque acc. and today while doing online banking on 30 Nov, I see they have taken R1000 out of my market link acc on the 11 Nov. - I am still waiting for ***** dept to refund my credit card R2400) and sort this matter out & every time I phone, they say they still investigating!!!! How long does this take from the 9 Nov to 30 Nov! They have credited my cheque acc with the R2000 and tomorrow I need to get yet another ***** ref No for the Market Link acc. I am really disappointed with Standard Bank & have been a customer since 1979.
