They lie to get you to pay more

So my service was suspended because i did not pay, on the 23rd of september i paid and then on my dashboard i saw only after making payment that i have no active services with them, then i called them and they said i must pay another R1000 and something to get reactived, so i wanted to make sure and asked them again because it showed i was in arrears for may but they charged me twice in may, so i also asked about that. They only then told me that once my service has been suspended i cant reactive it. So now i want to know, why they then told me if i paid R1000 and something it could be reactivated? I mean is this how they make money, getting people to pay more and then telling them it cant be reactivated? Its the worst service provider ever. And when i asked them why they then told me to pay more to get reactived they just didnt respond.
