Nobody Listening

My story goes back 17 MONTHS ago, a friendly representative of Telkom approached me at my workplace to sell me the LTE Router, after discussions of coverage etc, he assured me there was coverage in my area, after installation etc, I realized there was no coverage in my area, and immediately went back to Telkom to inform them of my dilemma, so which they responded if that was the case, they would cancel the contract, after numerous visits to the Telkom Shop in Hillcrest, and dozens of phone calls pleading for assistance, we are now 17 months down the line, and I have been paying R799 per month for a service I have not received since DAY 1, now my last debit order goes off at over R900, WHAT THE HELL!!!!! WHY IS NOBODY DOING ANYTHING ABOUT THIS???????? Today I had to take drastic measures and approach my bank to intervene. Why must we always have to be inconvenienced and have to resort to drastic measures. Why couldn't it be sorted with the 1st Phone call, or even the Telkom Shop visit. I've forked out over R13 000 for a service I've never had. What is Telkom going to do about this?????
