Bad service from RAIN internet service provider

I have signed up with rain 4G unlimited internet month to month contract. This happened last week Friday 05th. The next day I was sent an sms and an email stating that the sim was activated but I could not connect to the internet so I contacted an agent via the my broadband forum to assist since the customer care number just rang with no answer. After several attempts to connect I was told that there might be a problem with the rain sim so the agent ordered a new one for me. The new sim arrived on Monday 08th and still up to now, the 12th of February, I am still not connected to the internet. On the rain website under my profile it states that the new sim is still queued for delivery even though I received it on Monday.I have sent numerous messages to the agent on the Mybroadband forum for assistance but there is no positive outcome from him/her just empty promises. I even responded 4 times to an email sent from an agent ( Tracey Mthembu) from rain Cec who I thought would assist with my query but there is no response to date except when she asked for the ICCID and sim no. I gave it to her an have had no communication from her since. I am going to cancel this contract with the hope of getting my money back due to this bad service.
