Please if anybody can advise.  last Monday i put a chq in to Barclays from my neighbor/friend who i care for daily as a fee and for her food in to my bank for Barclays to immediately put a RG21M code and blocked my account.   They have refused to speak with me about the problem and asked me to call the fraud department to explained my self where the payment for £3,500.00 had come from.   I told them the truth for them to say we will get back to you within 1 working day.
