What an awful situation.....
Thank you for the financial info about paying for these works with Credit card or debit card.... And NOT Bacs.
I've mainly paid suppliers via BACS on my camper in the past, so a lesson to be learned here.
"The bank is also not able to help unless it was paid via credit card or debit payment. Unfortunately for us and other customers we've spoken to we used bank transfer which doesn't have any protection.
A warning to others, avoid bank transfer and use a credit card or at least a debit card payment instead. At least the bank will help recover money"
