Account suspended

I have 2 separate accounts with Cell C, which get debited on 2 separate dates - cellphone & 3G card accounts. For some odd reason, the R39 debit order for the 3G card was unsuccessful but the pmt for the cellphone account went thru. Cell C has now suspended BOTH accounts. I pay an average of R550.00 per month for the cell account! I feel I have been treated unfairly as my cell account is up to date - I feel it shouldn't be affected for a mere R39 account. I feel they are 2 separate accounts with diff account numbers and should be treated as such! I DON'T WANT ANYONE FROM CELL C TO CONTACT ME! I JUST WANT THE PUBLIC TO KNOW HOW CELL C TREATS THEIR LOYAL CUSTOMERS.!!!!!!
