RAIN TOOK TIME TO CANCEL MY CONTRACT AND NOW THEY MAKING UP CHARGES THAT I DON'T UNDERSTAND

I signed up for the Premium package with RAIN (R700) on JuLY 2021 and used their services up until I started having issues with the connection around September 2022.

I called in to change my debit date from the 25th to the 1st of of every month and TO COMPLAIN THAT MY INERTNET CONNECTION WAS BAD, in fact it was terrible, the consultant mentioned that they would have someone from their team call me back but they never did...first time where they said they'll call and they didn't but moving on to the payment issue as far as I know, if you don't pay you don't get access to wifi, if you skip a day of payment literally the next day your wifi gets turned off (which is fair) where am I going with this?

In January I called to have my contract cancelled and was told someone from the team will call in and assist cancel my contract(Second scenario), come January 1st I had no money in my account so they were not able to deduct anything and as I expected, no wifi, which was fair and having in mind that my contract is "cancelled" I disconnected the router and was using other network providers as an alternative which were more reliable for connection (VODACOM). Now they finally called me recently last week to tell me I have an outstanding R2800 and only to find out that my contract was not cancelled and I must pay that amount, the consultant mentioned that the service was not a pre-paid which I understood but if you don't pay you don't get wifi which I never got. The way I fought on that call not understanding how they were charging me for something I did not use and they know very well that if you don't pay you don't get wifi so how in hell were they still charging me for something I wasn't using??

Fast forward to today I get another call from RAIN and they were saying I should basically pay R1400 and they are saying they are charging me for the areas in December which doesn't make sense because they deducted R739 from my account on the 2nd December and as for January I don't understand what areas are those if I specifically called and asked for my contract to be cancelled in JANUARY-meaning I did pay for DECEMBER and they even took R39 more

I agreed to pay this amount on the 25th of May but I'm writing this feeling so ********** and disheartened. Why am I paying for December fees if they already deducted money from my account? I even have my bank statement to prove this and it's really upsetting, I don't mind paying for areas in Jan but no one is really explaining how my amount got doubled up twice, never mind the other months that I did not use so please tell me how am I paying for something I did not use (for Jan) and for the wifi I clearly paid for in December and I and the proof MY bankstatement which they won't let me send to prove this, how can missing payment in DECEMBER turn into R700 worth of areas 1 day?? no guys...I'm gonna share my story all over the socials as well, even if I have to pay this amount but I'll blast this as much as I can
