Not made aware of additional charges

I took a contract with cellc at the midlands mall in pietermaritzburg. Its been about 6months now and every month my bill has been around R588<br> I was not made aware that the promotion of 3gigs had to be cancelled by me and that i will be billed. When i checked my bill today it shows R1008. There is no way i am going to pay this amount i was not informed of it. Had i been informed i would have stopped it. <br> Is this how you guys trap people? Really poot service. I am going to take this further.
