Matrix Cellular — Bad service on europe prepaid sim card

Website: www.matrix.in

I took a Matrix Pre Paid card on 30th April 2016 for travel in Europe from 5th to 15th May. Was in Denmark & Germany. God bless them. They have a very bad service. I could ring outside numbers but could not ring up the local sim carried by my wife. Nor could the local sim call my number though in both countries we were using a local sim for calling back to India. The matrix people just kept sending messages: Valued(What a joke) Customer our technical team informs that your issue is now resolved. I kept sending them mails that the issue is not resolved but other than calling me up that we are sorting it out or that it will soon be sorted out or then sending me messages that the issue is resolved, Matrix did nothing about it.
