Two Cash ISAs funded same tax year

cartwright_g

My son opened a Help to buy ISA after being gifted money from his Gran, however he had already paid into an existing cash ISA this tax year and was unaware of the rules, he was only 17 years of age, the amounts are well below the limits, however his bank(Halifax) have just transferred all the monies for this tax year to his normal cash ISA, I know the HMRC would not have insisted on this course of action as would see it was unintentional and well below the limits, they would have likely sent a letter warning him not to do it again etc.  Halifax not being much help via webchat and helpline clearly very busy at moment, is there anything we can do to get this reversed as he can no longer make a one off payment of £1000 to the account come the new tax year but only the £200 monthly, or is it just a case of live and learn and start again, thankfully it does not look like they closed the HTB ISA so can still add to it from the 6th April?
