Pathetic resolution to problems and Unfair billing dates compared to payment dates

I have used Rain with no issues , as of the 20th of June i have no had any internet connection. i phoned numerous times and got told that the tower is down. i got switched to different towers , re-set as well as promised technician will give me a call. to date the network has not been resolved and no turn around time was provided. I have now cancelled my subscription. today i got debited for the month after being advised that i wont be. Yes billing is from the 1st to the last day of the month , but i have paid from the 20th of June to 20th of July for a service that i haven't used ( a month plus the balance of July) with no compensation or refund as i have not used it since the 20th of June. here are my calls 11th - *** - 12th July *** - 21 July - ***
