Tenant pays service provider

[Robert Beaupre]

I have a unique situation I rented to own a single family home in mass to a relative (lesson learned). The deal was we were to refi together but because of unforeseen circumstances I was unable to secure a loan relative took it upon them selves to start dealing with service provider thus avoiding me hoping to take over ownership I advised them numerous times that the service provider does not own the property I do. 

1. Can I evict for non payment because the lease they have is with me not service provide?

2.There is no 1-4 rider in the mortgage so the service provider doesn't have any rights and the fact I am not in default on the loan how do I get the service provider to stop enabling the tenant?
