I plead with the head of telkom mobile to please assist me as im not getting any assistance from your management teams at the telkom mobile dept.<br> I logged a case as im being charged for a device i do not have and was told that the matter will be resolved.<br> Now im getting invoices of nearly R10000 that i need to pay whilst im having a current contract with you which is up to date.<br> this error on your side is affecting my credit record as it shows on the credit bureau that im in arrears at telkom whilst im not as im being charged for a device i dont have.<br> My current contract is for a Samsung galaxy s6 edge plus which i pay R604.00 p/m but im also being invoiced for a samsung s6 edge 64 mb which i dont have with telkom.<br> The management team keep on promising me that it will be resoved and will provide me with feedback which they dont as my bank account is now affected as telkom tries numerously to debit funds from my account.<br> the device im being charged for was returned to telkom within the 7 day period after i received it and was informed that back office will cancel everything as i took a new device which is the S6 edge plus which im currently paying R604 p/m<br> <br> Please assist
