Pryco Sleep Diagnostics

The premium services costs over $ 7,500. At the time of signing, they were supposed to charge half now and half when you get your sleep apnea machine. They charged everything all at once. I was promised a contract but never received one. They claim to be a member of the AASM American Academy of Sleep Medicine but they are not. I contacted them directly to verify. At the time of signing, they were not a member of the BBB in which they claimed to be. The company they use to finance is GreenSky credit, which is for home improvement. The charge listed on my account says, «attic restoration.»
Why did they charge as attic restoration using a home improvement creditor company, for a sleep service study, lifetime monitoring services and a sleep monitoring machine? I don’t have an attic nor they provided services of home improvement for me. I was not provided with the documents they said they will send me (service contract) nor the machine. I called the credit company and cancelled the transaction as I found weird that they never sent me the contract and that they were charging the services under a different description than the sleep study services and medical equipment I was sold. Be careful with this business.
