The ignorance of Capitec Bank Staff

After asking numerous times in writing NOT to be contacted by phone, they kept on complaining that they tried to get hold of me. I am enquiring to use my debit card for PayPal. The staff point blank refuse to help me in this regard. At first Capitec bank didn't have a credit card facility, but changed because of customer requests. The bank and their staff don't listen to their clients. They point blank refuse to take their clients serious - they accuse me of not taking their calls, after I numerous times stated in capital letters that I am NOT available on my phone.
