You do not have enough funds for this transaction, Please recharge to use this service

Cell C and FNB eWallet, Money has been deposit via my number and I keep on getting a message " you do not have enough funds for this transaction, Please recharge to use this service" There is a ballance of R66, and 640mb Data on the phone and when I dial *120*277# I have called FNB and they have put the problem on Cell c, after 4 hours dealing with both parties the problem has not been resolved.
