No internet access but I've paid the full amount for the service

Bad service I've received from Cool Ideas, I have been calling and have been transferred from one department to another without any assistance. From the 31st of July my line was cut off after I've made payment for the month of August, I have not received any messages informing me that my line will be disconnected, I'm being told that my line was cut off because I missed payment, I've settled those payments before the agreed date which I was given by them, now I'm being told that Vuma cut off my line when I was told that every month Vuma gives them a billing for my account, so I'm not getting a clear answer why Vuma took it upon their selves to disconnect my line this time if they did not receive a command from Cool Ideas as always. From the beginning I was informed that if I don't pay I don't get service, I missed a month and I was charged for that month, which I paid to avoid long talks, now I can see that it means they always come up with stories that they change all the time, this time around I have emails stating that my line must not be disconnected and of the date on which I'll make the payment which I did. I've communicated this and was told that I'll speak to the manager, I waited on call to speak to the manager till now I'm still waiting for the manager, my money was received for this month but no service, not only is this unfair but it shows incompetence, especially when I have to explain to everyone of them when I call of what my issue is and not be helped, I have been on long calls and I'm still without internet, and still waiting to hear what must happen, now I must pay for a reconnection fee of a service that I didn't order to be disconnected, where must that money come from, who must pay for that fee when I didn't ask for it.
