Lack of service

I reported my aunt's phone line to telkom on the 15th of June, every time I phone to check why nothing is being done I get a different excuse. On Sunday 05 July I was promised that the phone line will be fixed Monday by 12:00. I phoned telkom again today 07 July, and was promised within the next 48 hours a technician will attend to the problem. I tend not to believe a word they say, its been almost a month with empty promises and still the phone is not working but when it comes to paying the account they expect them to pay, but they do not deliver any service.
