Pathetic Service

I've been using Isabella Garcia products in 2020 - I've decided to settle their account in full. To my suprised the company di not stop to dedcut their debit order even though the account was settled in full. I have notified them about this and I was informed that they would convert my money that was deducted into a voucher. So that i can then use the voucher buying their products online. I've made it clear that i do not like their products and therefore i need the money to be refunded back to my account. The communication occurred initially last year (2020) and now it is almost the end of 2021 and I have not received my refund.
