Bad service

On the 12 of February 2022 I went to mall of the North capitec Bank to replace my card because was expired. They told me is R70 to do replacement ok cool I don't have a problem, my problem is when I checked on my statement it shows that the charged me R70 twice what makes me cross I called their customer service number they tell me they see it but I need to go to that branch which is mall of the North and I'm telling them Im far from the mall at the moment but it seems as their service is very poor.
