Discovery bank flops!!

I contacted discovery bank this morning... who in my past experience, has always been very helpful. Albeit early in the morning. I was assisted or rather talked to by 2 consultants, 1 who did not do anything but talk over me whos name i didnt get and NEL who refused to give me hes surname on call reference ***.

I am disputing 2 charges and im being told i cannot reverse the charges as the merchant has not bank it. But i can see it has gone off my account. They also see that ive never used the merchant or signed up for any subscription.

Now im a fan of giving people a second chance but i dont believe i will be contacted by a supervisor. Because NEL condensedantly decided that he knows whats better for my account than I do. Discovery bank. Ive touted your services and customer service over the past months... but today you lost a customer because of how poor your customer service has gotten
