Non legal opinion:
No, not automatically, your information does not indicate "service contracts" they could have assigned the contract to you in escrow or you could have formally taken over the contract with the service provider company. In addition to the contract, review your escrow papers and check with the escrow company about this.
Their (seller) name is still on the contract and they indicated they are still bound by it.
What to do? Take over the contract in writing if you want? Have them pay you to take over their contract and release them? Check with a broker or attorney in your area for real estate or legal advice to be safe.
