This is sad. Surely a bank like Barclays should know better. I think they messed up and are trying to foresatll you from reporting them by mentioning that CBK is in the picture. This is hogwash!
Just let your mum, who is the one offended, do a letter giving all the details of what happenned and include any letters or emails that you may have sent or received from BBK that will support your position.
Address it to the Governor, CBK and attention Director of Bank Supervision. If you can, deliver it personally to CBK and let them acknowledge receipt ( this should not be a problem.). It is good practice to copy the Managing Director of the bank involved. Be as detailed as you can get on dates, times, Official positions and even names of the persons who you have been dealing with.
I can assure you that CBK is not holding any of your money. The money stays in the bank even when CBK orders a freezing incase of suspeced money laundering.
Have you tried to write to BBK's Headquarters?, Do you have any responses? They would be very disadvantaged if they received your mail( even e mail) and did not respond!
My take is that some fellow somewhere at BBK is sleeping on the job and trying to complicate things for whatever reason. I have always found it prudent to keep records of communication ( the the fellows resist writing ) .
Do not worry,I believe that you will be sorted.
