Vodacom contract issues

I am very upset with Vodacom vcontractors (telephonic upgrade department). I have 2 numbers that can upgrade and decided that the one i will upgrade and the other one i will stop for now. The lady i spoke to promised me that i will be saving on my monthly bill and also have an extra 1gb data free included in this package, also that i do not pay admin fee because i do the upgrade with her. Everything went smoothly with the delivery. I just had a gut feeling to follow up that everything on my account was as discussed and found the Admin fee was going to be charged, the contract i took has changed to an open line and best of all that the wrong cellphone number has been upgraded! I phoned the department to let them know it is wrong before the charges go trough and a month later speaking with a supervisor Mr Edhasen Moodley on ********** ive had no sucsess in resolving the matter! I dont know what more to do? There is more details i can provide and also my calls are recorded. Any assistance or advice would deeply be appreciated.
