No Respeonse/ reply on high interest rate query

I recently logged an Online query requesting an answer as to why the interest rate on my credit card was so high.(***)<br> <br> And 72 hrs later, surprise surprise, no response. This despite their promise of a 48hr turnaround.<br> Fnb charges me 7% more than the rate I receive from Nedbank . After being a loyal customer for more than 20 years this episode has made me re-think my relationship with FNB. <br> <br> <br> <br>
