One fine sunny day I De-installed a Nortel Norstar phone system from a customer and decided to go online to Sundance Communications and clicked a link to sell my used equipment.I ended up at Used Phones.Com website.Called them at 800-766-3425 and talked to Miguel who gave a price at which they would buy my old customers phone equipment.They Issued the necessary paperwork (P.O.)and agreed to the terms and sent the equipment to them.Weeks turned into months and after many calls funally got a hold of Mike Schmidt (the supposed boss).He found my equipment in the warehouse(I'm sure his mommas basement)and he said things were a little slow since it was Thanksgiving and would try to get a check out.............That was the last time my calls ever got answered.......Until today 4-3-17....Of course Miguel(Mike's accomplice who answers calls when he is not picking lettuce)said Mike was unavailable(Hopefully serving out his bench warrant for failure to appear according to others)..........Do not use either Sundance Communications or Used Phones.Com for any of their services.They provide tech support,referral lead service,phone,repair,equipment buybacks(LOL),tech forums and more for telephone technicians. A TOTAL RIPOFF
