No service from Sell direct

I am not the kind of person that goed to social media to complain, but i have no toher option here. I got a phone call from a sell direct agent 2 weeks ago telling me they have been contracted to telkom, My WIFI contract is up for renewal. The rooter and simcard was delivered 4 days later. I set it up and i cannot get it activated. I have tried to contact their office nr ********** numerous times. The line just rings until it cuts off. If you are lucky an automated recording answers that prompts you to hold on. This continues until the line cuts off eventually. It is now past my 6 day cooling off period and i very frustrated and irritated. I am cancelling this deal with you. I tried to do so within the 6 day period, but guess what!! no one can get hold of anyone in the company to be able to do so. I have sent emails as well to ********** . No reply from that as well Contact me Ilse : ********** 619. I want this deal cancelled and i will not pay the cancellation fee!! I will go and deal with telkom directly to upgrade my contract
