Welcome to the Community, @usmanswb92
This is something our team will absolutely be able to sort for you, so if you have access to another phone like a landline or friend / family member's phone, you can call on 07953 966 150.
Alternatively you can visit one of our retail stores for a free on the day SIM replacement, and they can help connect you to our team for the proof of usage request, too.
You would just need a valid passport or UK driving licence to pass account security.
