Bad Customer Service Lack of Understanding

I App**** for their service and I've had one of the worst customer service experience. I've communicated with about 10 Agents and None of them don t know what to do and why my Account isn't Activated. Instead all they say leave Device on and wait for 24 to 48 hour's. It's been more than 8 Days and I'm at my wit with they way they have handled my. Then thay wanna say it's a VUMATEL Issue as they are migrating to a new system as that is my problem. I've paided for a service which I can't even use. So To anyone I hope you Don't Pay because they can't fulfill their Service Level Agreements. Each and everyday they will come up with a different scenario.
