Internetcalls vs netTALK

I've hat a netTalk Duo tat worked fine for a few years. Over the last year it started going off line with the flashing red light. I had to reset it bu y unplugging it and then plugging it back in. This was happening more frequently, so when I happened to get an email solicitation from netTalk to upgrade to their new upgraded device the ezLINQ, I decided to give it a try. A week after I ordered it I had not been provided any tracking information. So went on line to call them up. (Found out that there was not a direct phone number.). The only two options were text messaging and email. I wad told it took two weeks for delivery. A few minutes after texting I received an email from USPS that a tracking number was provided but package had not been provided to the carrier. Two weeks later the USPS still had not been provided with the package. I texted netTalk again, After about 45 minutes the Customer Service could not tell me anything more than what I already knew. (there was a tracking number provided to USPS and they were awaiting for the package to arrive at the facility.). The customer Service said they would check on status and email me. After 24 hours had passed I had not received an email. I texted netTalk back and told them to cancel my order and to issue a refund to my PayPal account. Late that evening I received an email from USPS that the item had arrived at their facility. I texted netTalk that I had cancelled the order and that I did not want the package. I told them to intercept the item and to refund my PayPal account. They made no attempt to intercept the item. After more texting and they finally sent me a return Fedex mailing label and told me that once they received the package back that they would issue the refund. The package was delivered back to netTalk on October 2, 2019. I informed netTalk' Customer Service that the package had been delivered and to issue the refund. As of today there has been no refund issued and netTalk Customer Service will no longer respond to my text messages or my emails. I have initiated a dispute with my credit card company. BOTTOM LINE.....STAY AWAY FROM NETTALK.
