Terrible customer service

Nedbank as well as nedbank merchant services has been the worst bank ive ever been with. Customer service is terrible. After taking months to supply me with a new merchant device and to just get back to me . i lost so much money because i did not have a merchance device.They are still charging me fees for the pocketpos which i havnt used from December. My business banker from nicolway has done nothing to fix this. She did day she is sorting it out. I dont even receive responses to my emails. Worst customer service. I am suppose to receive a refund from dec on the pocket pos but she has not sorted it out. They will debit me again this month for nothing. Im so exhausted with nedbank.
