Really give up

I would like to lay yet another compliant, regarding my account I was on the straight 100 package, and received a sms on Saturday night saying I have being migrated I mean all of a sudden with even asking to change my package my account just switches over to prepaid without my knowledge and then my internet nothing works on my phone, I call the call centre on sunday they tell me they cannot do anything and cannot change anything, I must call on Monday and they tell me that I never had a BIS service but all of a sudden I call on Monday they re connect everything but then tell me I am not on prepaid but I am still on prepaid, its either you guys don't know what you guys doing or something is not right on your side.<br> <br> thinking of canceling this contract
