Missed 11 month warranty - no communication from tenant

[Sunil Kale]

Bit of a tricky situation here - my tenant has been paying rent on time. She is the first tenant in my brand new SFH in Katy Tx that i purchased in Nov 2023. I reached out to her about a month ago via text messages and calls (which were not answered) to schedule 11 month warranty for my property. But there has been absolutely no response from the tenant. I had my realtor go to the property in person(no one was home) and she also stuck a written notice on the door which stated that the tenant needs to call me otherwise the deposit will not be returned. It's been 2 weeks and I still haven't heard back. A couple of days ago, both my realtor and I called her number to follow up and the lady says the number does not belong to my tenant i.e. she's a diff person. However, the tenant was responding to me via text messages from that number till May of this year

Any suggestions what I should do next ? Should I consider sending a breach of contract / eviction notice ? 

What rights do we have to ensure the 11 month warranty repairs that were missed, are paid for by the tenant ?

Thanks !
