Cell C poor network with Vodacom

I've had enough with you guys. Since January 2021 I've had problems with my network coverage. You've been promising to assist me but you're failing. I'm on contract with you guys and this is what I.I paying for. Whatecer deal you made with Vodacom isn't helping me cause in my suburb Vodacom has no signal or rather poor signal. If you can't resolve this matter, please cancel my contract with you guys. I've been a Cell C member for years now, but this is what I get?
