Terrible Service and no feedback

The kind of service I am now getting from Finchoice is terrible.They are so good when they pursuing you for offers and when you have a query you are sent from pillar to post. On the 27th Dec I called Finchoice several times asking why did they debit my account twice and I was referred to Collections which I never got through. I requested a call back till today I have not received that call. I have called again today and again every time a consultant keeps on saying I am transferring you but again the call gets to someone at the wrong department. That's a very bad customer service. I was on hold and eventually I got to someone who's in Collections department but still told me she does not know what to do and wanted to send me back to customer care and when I refused she put me on hold to find an answer. I was on hold until I got cut off and didn't bother to call me back. Really??? what kind of customer service is that? There is an email I have sent on the 27th December till todate no answer. I'm still holding on the reference number 77156 – (FinChoice Reference) So now get the manager to call me ***. If this is not resolved then I will settle and close my account and I do not want you to call me ever again with your offers. Try me and ask FNB
