Tenant wont give phone number?

[Bob Romano]

My tenants phone has been working fine until the first month he took residence. Since then he has been consistently late by a few weeks for the rent.  Now I call it and it goes right to vm. I went to the house to tell him this and he said" his phone is being fixed and he had to send it out for repair" . well 3 weeks later , it still does not work. Now who waits 3 weeks for their phone to be repaired? I keep trying to call his wife's phone, she never answers' either. I sent him an email yesterday stating I need a new contact number and have not heard back yet. What would you guys do?
