Hello. I've been on contract with Three since around 2014/15. I'm looking to upgrade my existing contract as its due to expire this coming month. The problem is the registration requires some additonal details that i can't remeber! (I'm guessing new registration system since i last singed up 24 months ago). Information such as the date when i opened my bank account (can't find it under Santander either), and the exact date i started work at my current employement (been working there for years!), etc - are things that i have simply forgotten about. Would it be ok to put down an estimate date if i can't remember an exact date? If not, then i will have to terminate my time with Three. Thanks for your time, Allan.
