debit order never change for 6 months

We phoned 084140 and spoke with various call centre persons. We asked to please change our banking detail. But every month they keep on deduct money from the saving account and not from the cheque account. <br> What happens if there is no money in the saving account. The answer: Debit order comes back.<br> Then we start to get sms message to say that the account is suspended. <br> This is now month 7 month and again still the same message. <br> I mean really how difficult is it , to change banking details from a saving account to cheque account. <br> <br> So again this month we need to transfer money to the saving account so that the lines can be activated and don't forget its not only one line but both lines!!. <br> NOW I WANT TO KNOW WHO'S FAULT IS THIS ?<br> <br> AND<br> <br> Don't forget for every DEBIT ORDER that comes back we, must pay for it not cell c !!. <br> <br> SO CELL C WHO IS *****ING WHO.'S MONEY NOW.???
