Best Retail Services in Phoenix AZ

the WORST of the WORST Lied about service, lied about product, totally unorganized...cancelled service yet tech kept coming by to do service (lack of communication, right?!). Keep sending me bills for service not done. I sent lengthy description of what went on, including the BBB. Terminix is STILL sending me bills for service they did wrong/didn't complete. JEEZ. How do they still stay in business?
