Xciting 700i / Re: Clutch slipping?

Ok so I was so disgusted on Saturday I simply didn't feel like posting back up. I took the bike for a test ride (10 miles) and while it was improved it was still slipping on take off but I no longer felt I was taking my own life into my hands to make it through an intersection. I went back and spoke to the advisor who said they would have to call Kymco USA again and he once again suggested that it might be the bike breaking in yet. They had another one I asked him about which he said was new so when I said why don't you ride it to see the difference and received no response. I was a little disgusted and simply felt helpless to make them do it right so I simply collected my bike and left. It was almost like as a scooter owner I wasn't taken completely seriously.
When I got home I unloaded the bike and went for a 40 mile ride with no real change in it. Sunday it sat in the garage. Monday I rode it to work and noticed two additional issues. First at times at low speed there was some fairly loud noise (probably belt slapping) from the CVT. Second if I was rolling along at 10-15 mph, backed off the throttle, and then got back into it lightly there was a serious vibration/shudder (feels like the belt grabbing/slipping rapidly like clutch chatter). Disgusted I sent another email off to Steven at Kymco USA explaining the situation and the fact that the dealer I bought it at was an hour drive away one way.
Steven got back to me late in the suggesting a closer dealer that mostly deals with their ATVs so I made an appointment to drop it off there this Saturday and they won't be able to have a look until Tuesday.
Here's the thing that gets me. Was it the mechanic at the dealer not recommending to Kymco USA that the belt should have been replaced or was it Kymco USA that simply didn't want to spend the $75 (approx. warranty cost) to put a new belt in while it was apart? I can see a manufacturers/distributors point of view on not replacing parts unless they were needed but.
Now I do not know how far this dealer had torn into the problem since only the CVT cover and clutch bell where off when I went to look at it. If it were me (especially how easy this CVT is) I would have pulled it all apart (no mind you I don't know if they did or not) and looked over everything. What I felt is that maybe they only cleaned it without taking the belt off. My impression is the rep feels that the belt should be fine if it's cleaned however my experience says (assuming no more grease is going to come out of the pulley) that the belt should have been replaced because who wants a slipping belt until it wears off the layer that got grease on it.
I'm far from just a scooter owner with all my years in the automotive industry with the majority of them as a dealer mechanic fixing things. Assuming that the grease is no longer a problem I am certain that clean internals and a new belt would solve this issue. There is a lot of load in a small area starting off the line for the belt to handle and even a very small amount of grease on the belt will cause an issue under load. I would prefer they fix it rather than me having to do so (of course at least with me I know what was done though) since it's a new bike.
Problem is the belt slips and then the clutch doesn't engage fully until it stops slipping and spins up the output pulley. I can feel this taking off a moderate throttle, first engagement just over 2,000 rpm, once the road speed comes up if I slightly back out of the throttle I can feel a thud/bump and then the clutch is fully engaged and the bike is fine above that speed/throttle.
