Uniconnect — uniconnect team just did not respond

I bought a uniconnect sim card for europe. I was traveling for 25 days and trust me, my sim card didn’t work after the fifth the day. I wasted time emailing, since i couldn’t call. I even got on a wifi service to call the sales guy ajay to help me with the recurring no network issue. And there was no help from there as well. They chose not to respond to any of my emails and their sales guy was clearly not interested in helping my case cos he must have achieved his targets. Such horrible ethics.
