Please enter the first 2 digits of the bank account ending in used to pay your sky account

[Raspin75]

This is super confusing.  When you are asked for the numbers 'ending in' it's usually referring to the last 4 digits so I naturally thought it must mean the first 2 digits of the last 4 of my account. So for example if my account was 00123456, the account would be ending in 3456, therefore the first 2 digits of the bank account 'ending  in' would be 3 and 4. 
I tried this and it said it was wrong so then I inputted the first 2 numbers after the 00 as told and it was still wrong. I now only have one more attempt and do not want to input in case this is wrong too. Any help would be much appreciated

Hi @Raspin75  in case you weren't aware this isn't sky CS here just fellow customers helping each other. I would call sky for help.

I'd say the digits are 00 which are the first two of the account ending in 3456 in your example.
