RAIN IS RIPPING ME OFF AND I AM NOT NOT EVEN ACTIVATED CLAIMING I USED GIGS

1. Received my SIM on ***0, to my surprise I received two SIM cards. Called the call centre and was told to cancel on the web. The reason this happened is because the first payment time out and I had to do it again, however the payment was received on RAIN side for R1 x 2. I did cancel but was advised that I will still be debited twice and will be refunded for the one and to discard the other SIM. 2. I got home and inserted the SIM in my router but the password on my router was too few digits and was not connecting. 3. To my horrific surprise I received and an email on the ***0 to confirm that I have used up 3 gigs ????? The device was not even switched on for more than 15 minutes and switched off because it would not connect. 4. I called the call centre today at 1;23 and hanged on for 17 minutes and could not get this query solved. You guys are ripping me off. How can I pay fro 3 gig when the SIM was not used ?????
