Cell - C - Accounts Department Incompetence

I had a complaint re changing my banking details, it has been going on since the 4th of February 25. After putting my review on your platform the got hold if me but this has still not been resolved after me having to re send my two different banking details, I D, a copy of their statement and now another request for a bank statement. I sincerely hope this matter us sorted out for my next debit order. I cannot believe the incompetence if this company's accounts department.
