Can my landlord shut of my heat for absolutely no viable reason??

I've resided at this residence since 2008. Wonderful relationship with prior owner/landlord. Have taken on painting the exterior and interior of the house (all at my own expense since new landlord) and always, always paid rent and gas, electric & water on time for almost 14 years. (utilities in previous landlords name and new landlord agreed to leave them that way) Original landlord sells to new landlord and they raised the rent $100. It was cheaper to not move and I'd invested a lot of time and hard work and very proud of my improvements. Continue to pay all bills on time but manager (landlords mother) has literally "invented" drama. I paid Feb rent JANUARY 21st without including the gas bill (not due the 12th of Feb!) Manager sends daily text harassing me for the bill not due for over two weeks. Now I've been told he put in a shut off notice for the gas!! OMG! please help.
