From Bad service to No Service

I logged a call. Case ***8 at Telkom on the 19th of JANUARY 2016. They responded by telling me a technician will come to my home shortly to sort out the problem. <br> I asked Telkom to do this urgently because at home I keep loosing signal on all my devices. I cant use my internet I cant use my phone to make a call..nothing!! <br> On the 3rd of February there was still no technician. So I phoned again and talked to Thembisile who said no they will send a mail to the technician and mark it as urgent....until today 23/02/2016 NOTHING.<br> I'm paying Telkom a **** load of money for a monthly service which they are not providing. <br> Should I go to Vodacom?? I mean I know for a fact a client doesnt have to wait 3 months for a technician to attend to a problem!!! Or should I just cancel all my Telkom contracts????
