Unhappy customer with capitec

Hi. Capitec bank blocked me from using their bank so advised they will clear my name and I can open another bank account else where. They did says my name is cleared. When ever they wanted documents I sent to them! Went to open a bank account at another bank they advised my name is not cleared as yet!! It's 1 month!! Capitec needs to give me a letter to say my name is clear for me to open a bank account. How hard can it be to give a letter to a customer!! I'm running around and phoning them every day yet no feed back. I need a account ASAP!!!!
