Totally disgusted

I app**** for a contract with vodacom and after being given the run around for two days I was told that I was approved for the contracts I requested, I went in the next day and signed all the paperwork and received my devices. On my way home an hour later I received a call from the store to say that I no longer qualify for the package I signed for and they wanted to offer me a lesser package and I do not accept that and when I spoke to the consultant from the store she was crying on the phone to me telling me if I didn't return the devices she would be liable for them and would lose her job, I don't need the quilt trip because she is *********** I believe that I should be given what I signed for and not have to accept a lower package after the fact.
