BAD service, I am unhappy as a new client

Registered for their service, received sim and only worked for a week. Network LED is red. Reported and after so many escalations sim is registered on someone else. A new sim gets delivered, same issue of network LED red. 2 escalations already for the new sim, no response at all. I must be the one calling to understand when the issue will be resolved. If this in not resolved in 24hours I am canceling the service. This is uncalled for.
