@skidlidsid so long as the chain is 1/8 it should be fine with whatever.
3/32 chain and 3/32 cog+freewheel+chainring = working
1/8 chain and 1/8 cog+3/32 freewheel+chainring(whatever mix of 3/32 and 1/8) = working
3/32 chain and 1/8 anything = not working
Personally I would get a full refund and go elsewhere, can be certain that whoever fitted it didn't bother to locktite the threads or anything. I'd also swap to a 1/8 chainring+freewheel when you are next switching them.
