Ooma review: Poor customer service

Incident 8/4/2015, Incident number - [protected] Not happy. 2 phone adapters inside of 5 months failed(these were new, not refurbished). The first adapter was DOA and a replacement was sent in a few days. The replacement died and now I am without phone service for over a week. I am one of their "Premier Customers"...just imagine if I was a "basic only customer" . I will have to think long and hard about renewing service next year. Seems adapters are a weak point. off-shore customer service not very helpful. When the ooma is working, sound quality is very good. Asked for an extension on my service because of this major inconvenience and was denied. I am getting back $15 credit. Resolve? If these phone adapters are this unreliable, then I would like a working, backup adapter on sight.
