Bad service

I got a bad service from MultiChoice, i call them since in the morning i spend 110 airtime to call, and i didn't get help. I used to have 2 DSTV then i ask them to cancel the 1 for 110 and remain for the one for family package, and i pay 279 on 26/06/2020 but they disconnect it, when i call them every day they connected and works for 3 to 4 days then disconnected again, when i call them they said it escalated i will get call no one call me am the one i used to call and it charged me a lot of airtime. This is very bad service from MultiChoice. I need help and i need my Dstv to connected today because is not my that they didn't cancel it. And y they disconnect the one i pay. MultiChoice u need to treat the customer good.
