@tejaspatel, have you gone into the self serve to see if there is anything out of place in the account? Did a renewal take place recently? Check the phone number to see if it is still the right one. If this doesn't reveal anything out of the ordinary, perhaps check in with the moderator team to see if they can identify anything on their end. The moderator team can be reached via private message using this link. Please include a detailed description of the issue and the required resolution. This will speed up problem resolution significantly. Refer to the following knowledge base link for additional information on contacting the moderator team.
BTW, are you able to test the service with a different phone to see if the behavior is repeatable? This may be worth a try before contacting the moderators.
