Kiwi.com Refused to Refund My Flight Payment to My Bank Account

I booked flights through Kiwi.com and paid a total of 23,188.09 MXN (1,160.4 EUR) plus 199.83 MXN using my Wells Fargo bank card. On the 26th, I requested a full refund to be sent back to my bank account. Kiwi.com initially informed me that my full payment would be refunded to my Wells Fargo account within 7 to 10 business days. However, I have still not received any money in my bank. When I contacted them again on the 26th, they changed their statement and told me that they cannot send the refund to my bank and that they would only provide the amount as credit in my Kiwi.com account. I do not want credit because I no longer trust the site and I do not wish to use their services again. I am requesting that Kiwi.com process my full refund of 23,188.09 MXN plus 199.83 MXN directly back to my Wells Fargo bank account as they originally promised, instead of forcing me to accept credit.
