Good day I struggle for months now with Telkom. They send me a invoice for a landline that is on my name.i dont have any accounts at Telkom..i phone them and they told me to go to the SAP and do a avidavet to say that i dont have any accounts with them then i have to send it to a email adress they gave me that is not inworking. I phone again anfd again to tell them the email adress is not working.. Now i receive sms that they hand me over and that is not my account..i dont even have a work how can i have a landline.. Every thing is on my name .some where is someone busy doung ***** on my name and Telkom cant or dont want to help me to stop it... Last week when i phone again they just tell me to phone 10212 and that nr is also no working..i try the whole day but nothing. Please can you help me with this..This account is giving me a very bad name..
