Looking froa DME provider in Fort Worth, TX

Can any one help me find a DME provider for supplies and downloads that is in-network with Blue Cross Blue Shield? I recently moved to Fort Worth from New Mexico. The sleep doc I am seeing gave me a referral to Lincare. I have been trying to get in contact with them for 2 weeks, and no one will talk to me messages are left, but no one calls back, the few time I did get a hold of someone I was told I had to call a different office. Needless to say even if I do get someone to work with me, I'm already pretty sure the service will be lousy.

The sleep Center the doc is associated with was recently bought out, and the new owners do their own DME, and use Resperonics. I have a Res Med S9, as a result they don't have the equipment or software for my ResMed machine. Any suggestions and sharing of experiences with the provider are greatly appreciated.
