Telkoms bad service

I have been very disappointed in telkoms service i took my phone in for repairs 3 months ago to fix my charging cable thats all everytime when i get there,they tell me they dont get anything on the system.I have spend over R300 on traveling fair to find out about the phones where about but yet no one can assist me.The one worker sended the management a email about the phone a month ago but not once did he get back to me.I went back to ask again the,other consultant gave me a email adress that i must email to still no reply from them.I went back the consultant said,that i must wait till the one that assisted me is in.where must i gt all this money to up and down like this and yet for the 3 months i must pay in full for a phone that i am not using or a sim card which is so unfair.
