Poor after sale service - non-exixtant!

I lost my inverter for some unknown reason on the 6 December whilst away from home. On my return I contacted Goodwe customer services for assistance. At first I was impressed with the assistance that I received on the call, but later realised that there was no intention to assist me to have the inverter repaired or replaced, even after indicating to them that I wanted going away from the 22nd of December. They kept on asking me to send them video’s to proof what I was experiencing, and even with that, I did not receive any assistance. As it is, my inverter is still not working. Nobody made any attempt to even tell me that they will not be repairing or replacing it.
