25 spam calls in a week from FNB

25 calls from FNB in a week...I have called the call centre to ask them to stop calling...the not so interested agent said she would send an email to tell them to stop calling me. The very next day I received a number of calls again. I emailed ********** twice on 1/2February 2018 to ask them to make the spam calls stop...to this day, I have not had a reply from customer care agents. I eventually answered the call , as I could not take it any more...all they wanted to ask is if I wanted a credit card? 25 desperate calls for that? Stop doing this FNB. Send an informative email if you must. Stop harassing and forcing your products on me. If I feel the need for a product, I will come in and find out, or I will call you.
