Canceled service without my knowledge

Yesterday my wifi went off due to an outage in the area,this morning it was still off,so I decided to give webafrica a call to hear what was going on,to my surprise I found out that I have 3 services on my name and that my current one has been canceled without my knowledge,so now they want to tell me I have a balance I have to pay,for services I canceled in June 2024 and the other one in September 2024,now they sending me from one person to the other person with lots of different stories but no one is activating my current service,please just activate my service because I won't be held responsible for them not doing there work and not canceling the services I told them they must cancel,just activate my service
