Hachi Shears

I purchased a pair of shears in March of 2018. They were defective when I received them. I emailed the company and a representative named '***? exchanged them out for a pair of shears valued at $899.00 for the sale price I purchased. So far so good approximately a year later my shears started becoming defective pushing the hair and somehow not cutting. I contacted the company again since there is a lifetime warranty. That was February 2019. By email. There was no answer. I called and no one answers the phone. After 4 months of emailing, I finally got a response from a female rep and she forewarded it to '***? I have been emailing *** for an entire year! I get a response maybe once every 2 months even though I have emailed them over 100 times. *** finally said they would send me a new pair in December of 2019. Then never heard back. After another 30 emails *** said pick a replacement pair to be sent. I emailed the picture right back. Another 20 emails later and 8 more weeks and I have not received any shears it even a response. On their Facebook page this is happening to dozens of not hundreds of people. I don't know what kind of shady business this is but I'm out $150.00 and totally ignored by the company, Hachi Shears is supposedly out of California, USA. This company is taking peoples money and giving defective products if they get them at all and then doesn't answer complaints. This company needs investigated.
