Worst service by Telkom

I've app**** for a VDSL line 3 months ago, every time I phone the call centre they have another excuse and will escalate my call to their technical department that will call me back in 24 to 48 hours and every week when I call I'm being told this and they just never call me back in the 24 to 48 hours. Even when I demanded to speak to a supervisor I get told that they can't assist me either. This is ridiculous service to say the least and I highly recommend that people refrain from using Telkom
