Poor service delivery

I contacted a call centre after my service was suspended and made an arrangement to migrate from Compact to Access, I asked an agent the amount that needed to be paid including the disconnection fee, I went to pay the amount due, an agent advised that switching from one package to another doesn't happen immediately, she said it will take place during the night, well no problem, they then sent me an sms stating that from their side they can see from their side I am currently not getting any communication which is true, according to my understanding I don't owe them anything until the 26 of this month..so what I am asking from them is to immediately restore my service and I am not going to pay a disconnection fee, the self service also doesn't work at all, they can even retrieve a call recording if they want..***
