BAD SERVICE FROM WEBAFRICA

I have bought a sim card from the above company which is via MTN. The simcard is not working for 3 months now, but I'm paying via Dr Orders for 3 months without any service. I have raised this for more than 7 times , via their chat on their website its either I'm asked to hold or if they respond they told me to wait and later close the call. I called their call centre *** for 4 times, all the time my call get cut once they request my account details.
