Bad service from Vodacom

Very poor service from vodacom upgrades online. I did an upgrade via vodacom online about 2 weeks ago, i did not receive any communication / feedback with regards to the upgrade and i had to contact vodacom the whole time to follow up and the only feedback i receive is that the status is on back order and cant confirm an expected date of delivery. I made contact with vodacom online yesterday to cancel the upgrade and the lady i spoke to confirmed that it will take about 24 hours for the cancelation to reflect upon phoning vodacom again today its still not cancelled and this prevents me from canceling the contract with Vodacom. I need this to be resolved in a matter of urgentcy to enable me to cancel my contract and i would also like to have the information for pre-mature cancelations on all my contracts that i have with vodacom. In all the years i have been with Vodacom i have never received poor level of service like this ever, but this is the pits and then data just always magically dissapears.
