Terrible service from FNB Credit Card ***** Department

I have been struggling for nearly 2 months with an ongoing credit card ***** case. (case nr ***) I have called countless times, just to be told time after time that it has been escalated to management and I will receive a call with feedback within 48 hours. This has not happened and the best I have received is an email addressed to a different client. Please can someone sort this out, I find this level of service ridiculous!
