Hi Fevzi! I do apologize for the inconvenience, but the number was recycled due to inactivity last week. You did receive text messages from us previous to the number being recycled letting you know that it will be lost if you don't use it, as well as an email (you can check your spam/junk inbox).
Luckily, the number is still available to be reassigned to you, but please note that this is a one time exception. Should you lose the number again in the future, we won't be able to recover it for you
