Shocking service

We were contacted by a telemarketer and offered a package to upgrade our home internet and phone package. The result of it is we have not received what we were sold although we are getting billed for it and no one at Telkom is prepared to sort this out for us. Since 1 December 2014 I have spoken to 10210 and 10213 almost everyday. I have tweeted a complaint and I have left a complaint on their website. I have personally gone in to the Telkom branch at Longbeach Mall and was promised the Manager would call me on Monday 26 Jan. I have been given incorrect numbers to call, and numbers that don't exist. My query has apparently been escalated to the back office - really? Oh, I did receive an email on 27 Jan welcoming me to a world at my finger tips???? and congratulating me on choosing Telkom as my preferred service provider! Well actually I don't - I would like someone who is able to resolve my problem to contact me and sort it out or there is no other option by to cancel and go with a more competent service provider
