Poor Service

A couple of days ago I upgraded my contract through mondo with a specific package they had online. I received a text the following day saying the was a stock shortage. I spoke to a "service champion" today who was not very helpful telling me that there hasn't been stock on what i ordered for a while now more than two weeks. I am not satisfied with how it was handled as she told me to change my contract to something other than that as she doesnt know when they will get stock and that i must call mondo again once talking to a agent at mondo it was confirmed that it was not the first this has happened as MTN does not filter out their available product i have been woth MTN for about 3 years and this is the first time i am dissappinted in the service provider i would like feed back as soon as possible and i will not change the contract i app**** for because of mistakes made on a providers side.
