not enough information on upgrade

I called the upgrade departments in jan with regards to an upgade on ********** . I was given options of what contacts were available to me. I was interested in the samsung j5 with the 200 min, 500 plus 500 megs data and 200 sms at R 279 per month. I was happy to take this special. I was also advised that on the 7th of february there would be new specials out, I called in the 7th feb and was told that this package is not longer available. Should I have been informed that the contract package will no longer be available I would have done the upgrade in January. I have called the upgrades department on numerous occasions and asked a team leader to return my call. The consultant told me she will ask the team leader to contact me but she will not guarantee that the team leader will call me. I am still waiting for someone to return my call. The service from the upgrades department was of poor quality and they did not providing me with enough of information for me to make an informed decision. It seems as though Vodacom has no appreciation for customer loyalty.
