I never heard of any Colts complaints just watched the game and saw what happened. Not once but on several critical plays. This year they were not allowed to do it repeatedly though each team got away with some contact.
That game two years ago was the worst example of non-calls I can recall.
They complained for years that their receivers were touched by DBs but in this game the Pats got called (correctly) on an end zone call but the Colts got away with receiver contact when the ball was in the air and the receiver had position. That was a call that had serious implications on the outcome of the game which is not supposed to happen.
The other instance in that particular game when you had incidental contact or feet got tangled up are not things the refs are supposed to call.
