Reactivating my old phone number

[Nabs]

Hi, 

I have am unable to access my personal accounts as my old phone number has been set up on there. I have set up 2FA on my accounts but as my mobile phone was stolen the only other way to gain access instead of the MA app is the old phone number. Is there anyway I can regain access to the old number. I have called the old number and it is not active. It has however been over 4 years since I have changed my number but I have not cancelled my account with three at any point during this time.

Hi there, Nabs. 

Sadly, it isn't possible for the team to reactivate a number after it's been deactivated. Sorry about that. You might be able to contact the company in question to see if they are able to deactivate the 2FA that's locking you out of your account. 

Pete.
