Recently my account got blocked after attempting to send £4,000 to my parents. My account is 3-4 years old and I never had a problem with the bank. I usually get adsense checks (around £1200-2000 monthly), which hasn't been reported to HMRC yet (tax year 2014-2015 deadline is next year). Since everything on my end is legitimate can I ask for compensation from my bank for blocking access to my account (online only, I can still spend money in shops)? How do I go on about this, should I visit the branch? How much will they compensate if they do pay me?
