Might as well close my account

Monday 09/03/2015 I did an upgrade online and within 24 hours a lady called me back to do all the checks and told me my account will be migrated which was done however, i only received 100 minutes, but no one can tell me what happened to the 200 smses and 500MB of data i was supposed to have received. two days ago i was given *** and i have been phoning for the past 3 weeks and i have discovered that your call centre agents are a bunch of pathetic *****. I was promised the new phone within two weeks and now the 3rd week is ending with no ****** new phone, no smses,no data bundle of 500MB, my debit order was supposed to be R499.00 but you still went and debited me with the old amount of which was on a different package and i have nothing for it. Every time i have a problem with your establishment, nothing gets resolved instead your call centre lies and make false and empty promises. therefore maybe i should just close and cancel this contract and go to a different provider that will treat me as a human and appreciates the fact that i pay and never default. this is just complete ******** and i am now gatvol with your nonsense
