If your issue is not fixed by the agent who picked up your phone, a trouble ticket will be generated and you should get call normally within 24 hours (please make sure you provide your cell phone and pick up the phone to avoid delay in solving the issue.), if the 2nd tech contacted you and could not solve the issue, it will be escalated to level 3. Most of issues are solved or provided solution within 48 hours from the trouble ticket generated.If today is your activation day, because of provisioning might be finished before end of the day, so you might not get call back on the same day and the troubleshooting will start from 2nd day after midnight.
