Finchoice Mobimoney

I had a loan and a mobi money account with Finchoice,I settled both accounts and I called in to close the account however the loan account was closed but the mobi money account says active and says 0 withdrawal available,my issue is why keep it open if I can't use it when I clearly asked to close it after settling it ,also after settling there and amount Of R98,00 written settlement amount so who is supposed to pay that when I have settled the full amount according to the settlement letter I received..why is the mobi account active if I can't withdraw from it why was it not closed ?
