Unhappy RCS money card client

I wanted to change my personal details telephonically and got some of the questions wrong, then they blocked me . I went to the branch and from the westgate game branch they emailed them a copy of my id and signiture. They called them to confirm if they received it but they couldnt get thru. I called them from work the next day and advised them of that and all they said is they didnt get it. I called now to find out what my available credit is and they refused fo help me. I find tbis very anoying as i am still blocked and they point blank refuse to help me.
