Bad after sales services

Sold me nonsense, told me I have good Telkom coverage in my area, on receiving my router etc, nowhere in my town the router picks up a Telkom network. Logged a complaint on 17 April 2018, last feedback received after several mails was 3 May 2018. They are waiting for Telkom to revert back to them. How hard is it to pick up the phone? Debit order has gone off from my bank account and I didn't even make use of the internet service at all. I also logged a query at Telkom on 25 March 2018, after I called them twice no one called me back. My case number at Telkom is ********** 6.
