Such a frustrating co to work with both locally and nationally—-VERY unfriendly ppl—-incompetent—never get what I order—last order over 1 year ago I ordered 2 nasal pieces—-I received 5 (got charged for 6) and a headpiece—called local office and was told how much it would cost if I kept it—-it was TOTALLY wrong—received a bill for $132.00 which I payed—-11 months later I receive another bill for $49.00 for I don’t know what as I haven’t ordered anything in a year—-the woman I talked to was so RUDE the I yelled at her and hung up—-I will NEVER use this company again!!! Was told no bills had been sent out in 6 months—-this company is SO mismanaged I cannot believe they are still in business —-DO NOT USE THIS COMPANY!!!
