help stopping a progress thief

I have had this happen to me twice in two days and it has been the same player. Yesterday I was in first place in the weekly race and when I finished a level it showed the player in second place now had my total levels for the week and I had theirs. Support was useless and sent me a form letter that basically said sh** happens. I shrugged it off and made up the levels (35) and passed that player and was 100 levels ahead of them. Same thing happened this morning I finished a level and there again the same player who had been in 2nd place now had my levels and I had theirs. Anyone have the same experience or a fix since game support is no help
