Matrix Cellular International Services Pvt Ltd — Mobile data not working

I recharged my matrix global number a 28 day unlimited (voice) & 10GB data package for Global sim. I was promised 4g and data at high speeds. After recharge i was able to make calls but the data was not working. I complained several times and the technical support recommended i change the settings to 3g and blamed the speed on coverage. I can not use the data while i am away from home. I had to depend on some one else data or any wifi, where i have 10GB data. They are not really doing anything to solve my problem. Send the images & video of my data not working. But still there is no help.
