Harassing Sales Callsc

I opened an account with FNB over a year ago and have received exceptional service in terms of actual banking services. <br> <br> However, of late I have received sales calls up to 3 times a week offering various products to the point where it has become a hinderance. <br> <br> I emailed FNB about this issue, and recieved a reference number of 665976. However no one has contacted me about this nor seem to have taken any action in this regard as I again recieved another call this morning. I now recieve calls twice daily if I do not answer.<br> <br> I suggest a note be made on the system and if I recieve another sales call, I WILL CLOSE MY ACCOUNTS.
