False adverti*****t and ridiculous billings

firstly, rain is a month-to-month service, you don't pay they cut your services. I am sitting with a balance of R2500 that they say I'm owing, Rain has no binding contracts, it does not bill in errors hence we purchased. i call the finance department and i get to speak with people who know nothing about the products, and they even have a nerve to lie to me. and the nerve to even hand over our account to debt collector's sis

write off the balance cause i dont owe anything.
