Subscription *****, rather cancel and subscribe to alternative isp.

I did not pay my account for august month due to tight budget, i was told to pay my account before 31st aug or my acc wil be terminated, i paid my account on the 27 august for september month, now my service is being switched off because i did not pay for september, my payment for september is now being used for august month after i emailed afrihost to explained my situation for august. This is a month to month contract, how can afrihost debited me a full subscription fee for the month of august if not a single days internet has been used? Accordingly to the accounts team this, was in the t's and c's. Now i must pay a full month again of R847. 00 zar to reactivate my account. I must pay R1698. 00 for only september month.. This is day light robery. Mind you this is only for a 75 to 75 mbps fibre line. I contacted the accounts department where my phone call was cutted off. I do get it yes if i did not pay for august month an additional 25% fee of the debited amount for the activation of the line is more than fair enough, but to let their customers pay for the full month subscription its just absurd. This is theft. Not cool. Not recommended. Not helpful at all.
