Useless staff. ****py System

Currently doing some renovations at home. The builders somehow managed to do something that stopped my home phone from working. I tried calling 10210, which is hard if you don't have a telkom line, sat on hold for almost an hour listening yo really bad music. Eventually visited the local telkom branch, the lady logged a fault and I was told that someone would be at home in the next 2-3 days. 2 days later I get an SMS saying the issue is resolved. But it still wasn't. Paid them a visit again. This time apparently it went up to the technical manager. 3 days later. Still nothing. Paid them a visit again yesterday. The rude lady at the counter had to finish her conversation before she even acknowledged me. And then she proceeded to tell me how useless she is at her job and she couldn't help me. How can your customer service be so bad?
