I was on the middle ring at front, and middle at back. I don't think the big ring is wrenching it on a mountain bike. Speed approx 14-15mph
Not sure what the hub has to do with it, unless I don't understand the term. I thought that was to do with wheel.
I have seen chains jam in between the frame and ring, chains jam in the front deraileur and chains jump of the front. Maybe my explanation was descriptive enough. My fault.
I just wanted to know if it makes sense to go in there and go "Hey, when I cycled on this bike yesterday it was safe. When I cycled on it today in the same manner it threw me off. What you going to do about"
Has ask.fm made people all wary of trolls. Thought I was just asking a fair question, sorry if I used some terms and not others. I name the bits I know, just as if it was a car, I could point to the battery and change it but wouldn't be able to point to the ECU and describe all it's functions

Considering the info you give you leave out so much to try to get a handle on what you are describing.
For instance:
What hub? I'd guess rear hub but you don't say.
Age and type of bike. Makes a difference when trying to picture the situation.
What gear were you in in the rear.
I've never heard of or saw, in 20 years of shop wrenching, etc., a chain wrap around the "front" derailleur. I also find it curious that you know how to use some terms/words but are incorrect in others...ie. "front cogs" instead of big ring or front chain ring, "cogs" instead of teeth...just find it odd.
I'd not consider worn chain ring teeth as the problem. Typically the front derailleur will toss the chain off the chain ring to the outside where it can wrap around the crank arm or bounced it inside where it winds up sitting on the BB shell.
"Chain Wrap" generally occurs when the chain wraps around the rear derailleur. This often happens when the load on the derailleurs is great and when the springs recoil the snapping action can wrap the chain around the rear derailleur.
I am also surprised and find it interesting that you are already shifting onto the big ring within 100 meters of riding. What gear were you in on the rear cassette? Were you in the biggest "cog", most teeth, or near it and under slow speed and heavy load trying to shift onto the big ring causing a significant cross chaining? I've seen people trying to do this while pedaling slowly and just grinding away as well as the heavy angular load is not good for the drive train and can cause bad things to happen.
My suggestion is to determine if the work done on the bike was adequate and properly done. If not I'd have to think the shop is responsible for making the bike "right" and possibly for the injury but that is a legal issue. If the bike is fine it is "user error" and you need to learn how to use a bike in an efficient and "proper" manner.
There is a lot missing from this tale and I'm also wondering if this is someone "playing" us/me or a troll.
We'll see I guess.
