Rain does not live up to promises

When i took out the rain wifi services it was +-R399 per month i had the wifi for a few years not because i wanted to keep it but because i had no choice firstly i never had signal and when there was signal the router just went of i tried and tried the get hold of rain but to no avail yet the price of the wifi went up en up i ended up paying almost R700 a month where i took the R399 ***** plan option .

So i get hold of rain bots and they said someone from rain would phone me One year later no one phoned and in that time frame my wifi was off in a box didnt use it . So eventualy someone phoned me after a year and told me they record the phone calls for safety and what so i told them i have email where i cancelled my wifi with refrence number and they must sent someone the pic up my router then the lady said my account is in arreers they cant cancell my wifi or pic up the routwr then i fight with them because they take money from your account 2 every month and you cant stop them they are ***** so they told me oky everything is fine they said they can see on the sistem its blocked and of and they will send someone to pick up the router ,and they did but messages did not stop they stil want money from me keep phoning me eveyday non stop for payment .

Please help
