Rain is useless! Stay away

Rain is a very funny internet service provider, I have been with them for years and I really don’t know why I don’t just move to MTN, on Friday they give me a option to part pay R595.00 then a 3 days later they switch off my internet, what’s the point then of giving the client that option if you are just going to **** them! And switch off the internet without any communication, if I don’t get my internet switched back on I will just migrate to MTN, I have honestly had it with rain
