No support for customers!

I am not sure whether the network is worse or the customer support. They have terms and services which say if you return within a month from delivery you are eligible for a full refund. I used the device for 2 days and logged a return request and I also have an invoice which has a refund due on it. The refund was due on the 1st, which of course never came. The support team does not respond to emails. I called them and I was put on hold for 17 minutes and ghosted by the support representative. I had to call back and try my luck to see if I could find someone who is actually willing to talk. All in all, this is a recipe for disaster.
