RAIN INTERNET POOR and SHODDY SERVICE

This Rain is in telecommunication but they do not even have the decency to communicate back to customers that have paid!!!!!!! I have been trying to RICA my sim with them for 2 weeks now and they have validating my address ever since. The emails that I have sent to them are countless and they have not even had the decency to at least acknowledge receipt let alone assist in solving my problem......... Makes me wonder what sort of service I should expect from them for the first month which I have paid for already?????????????
