Rain is a trap and a ****

I have been with rain for more than 5 years, I 1st used their 4g plan that cut off data at around 7 to 11, it was a bit of inconvenience but I got used to it, adapted, because it gave me time to spend with family especially my son. Over the passed couple of years I then upgraded to their 5g unlimited data plan that comes with a router. It was good at 1st but my issue now is, they keep charging me for data they don't provide. I missed a payment given there was no money in my account on the debit date and my data got cut off, but every time I come resolve, I find that I have been charged for data when my service was suspended and have to pay large amounts even though no service was actually provided to me. I was told it is a month to month contract, shouldn't I not be charged for the months Rain itself has restricted access to their data. I only app**** for Rain so that, I always have data access at home, but find myself having to spend buying data for my whole family individually because there is no access to the Rain data but somehow I am still being charged for data on month to month basis. I did not sign a 2 year contract deal that comes with a device and minutes like a MTN, Vodacom, cell c or even telkom offers. I subscribed with Rain for a month to month agreement and it's not my fault there was no money in the account listed, I have multiple accounts with different banks and I could easily transfer the money from my other accounts, problem is they say I must pay R4130 for the months I didn't even have access to their services. Why suspend the account if they not even providing the service we agreed upon. They making money off people but not giving them anything in return. The agreement was I pay for the month I already used their data every month on th 1st, but now they want me pay for 7 months I didn't use. Another thing, I assumed the router was being faulty when it didn't work but it turns out they switched off my data supply and still want me to pay for it. I would like to pay for what the one month I know of that they were actually servicing me with data but I feel they to need to compensate me for not delivering any service to me, they need to review or change the way they operate because it is unfair on their customers, Hoe can a person pay for 8 months when rain only provided data for only one month. Rain is milking us for being their client but don't provide anything in return
