Warning... Please do not purchase a reburbished model from BuyYourOwnModem.com. They sell modems that are registered to other customers, which cannot be authorized or used by Optimum customers. Waste of $ and time. This company does not have a customer service telephone #. I tried to resolve my buyer issues with multiple e-mails with no resolution. Seller refused to refund return shipping for selling me inauthenticated modem.
We are sorry to hear that you had problems with your provider as we have installed TENS OF THOUSANDS OF UNITS on the Optimum network and after reviewing your order the item you received does not even have an Optimum part number on it for the one rep you worked with to make such claim and so it isn't possible or this to be "pre-registered" to them and unfortunately this is a game some reps will play at cable companies in order to try and get you to rent their modem while they collect a commission in the process for getting you to rent. Per our purchase terms we do state that the buyer is responsible for return shipping and offered to cover yours if you could just get a simple work order or document from Optimum validating such a claim but of course since the part number wasn't theirs they wouldn't dare put such in writing and so we never received anything from you or them so we could follow through with our offer. We would have strongly encouraged you to work with a supervisor to get the matter resolved for file an FCC complaint if needed or we would have been happy to call them for you if you had provided a number of contact but unfortunately we never received such. You have already been issued a full refund for the trouble that Optimum caused you and we became the victim by eating the shipping and labor costs on our end but unfortunately did require you to return the item to qualify for such refund as we are sorry you were not happy about that. We have been in business almost 8 years now and have strived to accomplish over 96% positive feedback on Amazon and Ebay as a power seller to go along with over 3000+ positive reviews on our websites so I would say we aren't perfect but most of our customers have been quite happy with our service. We are again sorry it didn't work out and that you had an issue with your provider and wish we had more control over their business practices that caused you to need to return your item for a full refund which has already been issued.
