I am not a meditronic user, as I have an accuchek, but I think that you should have received more training before you got the pump. Not just which buttons to press, but also in carb counting and dose adjudstemnt! If you have not had teh training to do that, then a pump will not help...as you have to understand your diabetes care enough to be able to use it.
What a shame! You clearly needed more support, but I am surprised that you took teh pump back! Try and do teh online Dafne course, and see how you do with that? Then, maybe revisit the pump again?
I don't think that it is down to the manufacturer to do this. YOour HCP should have made sure that you were ready for the pump. I got my pump in Feb...and had my first follow up appointment last week...so it really is something that you have to perservere with.
All the best
