Horrible company. Horrible service. Poor call quality, cannot fax. Broken calls. Have to use my Cel Phone for "quality." Every time I've called Lingo technical support I reach someone with broken English in India who told me it has to goto a Level 2 Technician. No one, on both occassions, called me back as promised. Then to add insult to injury, they'd send a damn survey each time asking "How Did We do?" One time I received an email saying they were unable to reach me. I have caller ID display and history for WEEKS. They lie. I then emailed customer service about this asking for a REAL call back and they have yet to respond and it's been 2 weeks. When I 1st started with Lingo they offered a 30 day money back guarantee. Well it took them 4 weeks to port my # from my previous provider, Comcast. So by the time I was able to try the service out, the woman in customer service said my guarantee had expired. I explained I HAVEN'T EVEN BEEN ABLE TO TRY IT. 1 week of my guarantee was waiting for the damn Lingo Router to arrive in the mail. As you can see I'm very frustrated. If you want call quality, Lingo is horrible. If you need to use data services with ANY VOIP service, stay away until technology improves. I've had Vonage before as well and faxes, hooking up to Satellite receivers to dial out, etc. have always been problamatic. Lingo has been disgusting to say the least. Vonage was much better, still with issues, but at least Customer Service appeared to be in the United States. Horrible Customer Service, Horrible Technical Support, Horrible quality. I am going back to a good 'ole fashioned POTS Line with Qwest. Damage Resulting = I am a Real Estate agent. Hundreds of dollars in gas having to drive 10 miles each way to our office to make or receive a fax. Extra large Cel Phone bills as call quality is so bad I have to call customer's back on my cel. Yes, my cel phone is crystal clear, Lingo is horrible. I have a 7 MEG DSL connection with a 700K upload speed. My internet speed is NOT the issue.
