Telkom the worst service provide so far

The horrible service and appalling behavior leaves one amazed i went to Telkom Hatfield to hand in a device that is not charging to may shock a Thato Moentshe told me i cant hand in the device if i dont have a receipt because they cant print my details in order to have the phone booked for repairs even though i had my ID and proof of residence, can someone clarify for me what am i supposed to do with a device that is 10mnths old still under guarantee and i am paying for but unable to have it fixed because an employee claims she and all others at Telkom stores dont print never mind they have my details on the system as a contract customer. i subsequently called their customer care line and spoke a Palesa who once again failed to assist then gave me a sales number to call which i did and ended up dropping the call as it rang without being answered. someone me tell what s the use of our details on the system. the only highlight i was there to take another contract and was saved by the disgusting attitude.they dont even deserve a star rating - 10 is more like it
