Billing problem - No solution to date

My wife opened a business in 2014, she had a personal FNB Bank Account used for the business.<br> <br> One day she got a call from Cell C offering her a contract (note: Telephonically), got the handset & everything delivered to be paid for via debit order<br> <br> Unfortunately the business closed down & no income went into the bank account, we asked Cell C to change the banking details & they simply refused to do it telephonically & advised us to go instore. Evenutally done that & we had a very bad experience instore & I refused to give the store whatever they needed to do the change (Proof of Income, Proof of address, Bank statements, Consent forms etc)<br> So I started paying the contract amount every month manually via EFT, R168.00 every month.<br> <br> So now the debit order keeps bouncing because of the bank account not changed & Cell C keeps penalizing us for this...! After several calls with the Collections department, it still happens! Even went instore<br> <br> Cell C also has the audacity to suspend the ****** account every month however we pay accordingly<br> <br> We have not been able to use any of the services promised on the deal, airtime, although I do pay. Collections also not willing to provide solutions.
