Rain month to month shady deal.

Rain are ****** when it comes to this month to month no contract. I tried cancelling my premium 5G service with them as I moved to another service provider as their service is not consistent and I cannot work like this. I call and the lady Nokulunga tells me "You can't cancel because you owe 2k for the previous month." I'm like, but this is not a contract and just like any other month to month service if payment is not made, services are cut off for the following month. So she says (and this is where they catch you), "No we give you a grace period of 3 months where the service remains open and if there's usage for those months then you are liable for payment so you can't cancel." What nonsense is that? That sounds like a shady contract deal to me. As a customer, it is my right to cancel a service when I am no longer happy with the services, so please cancel my contract. Other users are complaining about the same thing and this is a ******** act and infringement on consumer rights
