Buy Your Own Modem

I ordered a modem for my DSL home network. The product I purchased was: Actiontec GT784WN DSL Modem/Wireless Router - 300 Mbps (TDS, Windstream, CenturyLink, Other DSL providers approved) for the amount of $109.94. When I received the modem it was in a used beat up box with a photocopy of instructions to follow using NETSCAPE (which does not exist any longer). I was able to connect the modem myself with no issues and was able to get online for a full day. After that, the modem would not work and would go on and offline. I reached out to the company via email (they have no phone number or contact information listed other than email) and the person (gave no name) that I purchased the wrong modem. Which is not true. The modem I received was from the 2000's and was very old and antiquated. The person told me to send back the modem and they will test it. I still have not received my refund. When I inquired about my refund they immediately refunded me $74.94 and told me it takes 30 days to refund (which was well over the 30 day mark). When I asked why I was not refunded the full amount they said that it is because I purchased the wrong modem. Which again, is not true. They tell you to read the terms before purchasing the product and it does indicate that a full refund will not be granted if you purchased the wrong modem. I've read other reviews online and the same experience has happened to them. They profit off of selling antiquated, broken equipment to consumers and keep 30% of the sale when the product is sent back. This business is practicing a bait/switch technique and stealing money from consumers. Please look into this company and read reviews online. Yes, there are very good reviews online but my gut tells me they are fake. This company is definitely working a scam. The person at the company is dismissive and accusatory. Reported to the FTC, BBB, and AG. And as a small business owner - my lawyer agreed to look into this company's malpractice. Although doubtful anything will come out of it at least I can report them here and other sites. Buyer Beware.
