Telephone line & Wi-Fi not working

Telkom Called me on 4 Feb to offer to upgrade my line. I accepted & the order was placed. My new router was only delivered on 26 Feb. As always waited forever to get a response when called for assistance to instal the new router. Everything was working fine after it took 4 hours to set up. My 2 Meg line was now a 4 Meg line. By Monday evening I noticed my line was static. Could hardly hear the person on the other line. Tuesday 1 March I logged a fault online: 20CWK010316. By Tuesday evening my telephone line was dead and my Wi-Fi has not been working. I tried to log another fault but it wouldn't allow me to. I received an sms on Wednesday 2 March advising is in hand with the technical repair divisioin. It's now Friday 4 March and my line and wi-fi is still not working. The thought of trying to phone the call centre and wait for an hour is not something I have time for! I'm hoping that someone from Telkom will call me to tell me what's going on???? Regards
