I would like to write a review about Rain Internet Service Provider

I would like to write a review about Rain Internet Service Provider. Their service is terrible, the agents are not audible and cannot speak English. My dad’s not been connected from late last year and yesterday he was told he owes R2000,00 yet Rain is known to be a “prepaid “ service provider. If you don’t pay you are disconnected so how would he have incurred R2000,00 debt. RAIN do better and get call agents who can actually speak English. Very angry and frustrated
