Bad after sale service

<div>OMW, the after sale service is so disgusting. I bought 4kv silent invetor in Jul 2022, I took it in as the start button was no longer working. It's been a month now they can't sort out only the start switch, the machine was still working perfectly. It's difficult for them to even give a quote on machine service. I won't recommend anyone to buy this brand.</div>
