terrible service and empty promises and billing

I got a 2nd contract with cell c in Feb.1st of all the consultant got the sim card number wrong! I couldn't use my phone for a week and a half. I asked to change this at another cell c store and they told me I would have to pay even though it was not my fault if I do not do it at the same store I got the contract at,which is 20km away from where I reside!I still had to pay pro rata for all those days I couldn't use the phone.Secondly,I ask the lady to put a notice to cancel my first contract as soon as it expires and make the debit order at the end of the month.Not done!15th I received my first debit order and I was very upset as I only get paid month end.I also realised that I didn't get 1 GB data to use anytime (as per the consultants word).Instead the data was split in 2 which was not communicated.the other 500mb is useless to me!I called cell c immediately to amend this again so the debit order is at the end of the month! Bam! On the 15 I get a sms:cell c has deducted money.Really?How many time must I tell you to debit at the end of the month! How many times must I tell you to put a notice to cancel my other contract?At this point I am really fed up. I wish I had gone with MTN
