Wonga ******* debit orders on my bank account

Wonga Finance have actively refused to remove the debit orders they have loaded onto my account.<br> This happens after I have pleaded to them to do so.<br> I have paid this guys in full and I have received a paid in full letter from them, however they still send me annoying threatening SMS's and emails that they are trying to get hold of me when they themselves are not responding to my plea emails.<br> I have called them 6 times and emailed them twice requesting them to unload the debit order they refused.<br> On their website it still reflects that I still owe them.<br> someone needs to resolve this as I don't owe this people how can they insist that the debit orders will still go through when I don't owe them, and also after I have advised them not to.<br> Surely this is not a compliance with the credit and consumer act???<br> It is sad to see people are still abusing the debt collection act.
