Still awaiting contact from Credit Card Support

I recently had 2 issued I needed resolved by FNB. Their response was quick and efficient but since solving my original query I am yet to hear from them as promised regarding my credit card issue. I was told to expect a call from a consultant last week but as of yet they have failed to contact me.

There is also no response to the emails I sent last week and after getting such great service initially it seems as if it was short lived. I find it rather frustrating and disappointing that one has to constantly follow up with them. As a customer I was told the bank will be in touch with me and that has not happened.

Here is the email I received as proof (I have blocked out the details for privacy):

Good Day ***** ******* Your Complaint with ref *******NF has been assigned to a Resolution Service consultant in Credit Card. An investigation into your matter will now be initiated and we'll be in-touch with you shortly.

I would like to resolve this issue as soon as possible.
