Rain Internet Service Provider is a pure ****

Rain internet service pure ****. i received a sim card but am given runaround when i ask for help to connect, i spoke to a lady by the name of Thembeka and fattima and none of them could help with connection or delivering a new sim card. now they are not even replying to my emails and calls when i ask for a refund since i did not use their service as per my agreement with the company
