Is the answer staring me in the face?

Well i changed bank accounts in December last year, from Bank of Scotland to Halifax ( who are same company ) so when i asked about getting my recent bank statements they advised me they couldn't get " official " statements as the account was now closed, so they printed them off in my local branch on just normal printed paper so i asked the bank manager to stamp each statement.. each statement just shows my name account number etc, type of account and my address.. and mentions the town of my local branch, no official Bank of Scotland head paper or anything.. hence the reason me satying im a little bit worried this isnt official bank statements.. spo i have 3 months of those statements and 3 months of official Halifax statements, so i thought maybe best to include all the literature from the banking switch confirming both account numbers etc etc..

You should be fine with that, no worries, especially with the letter from the bank.
