Unauthorized Hint Charges On My Account

I use a Chime debit card and on May 24 and May 25 unauthorized charges were made on my account by Hint without my consent. On May 24 at around 11:41 a.m., a transaction for $22.80 was charged to my card. On May 25 at around 9:41 p.m., another transaction for $28.06 was charged. I noticed these charges while checking my balance and I did not authorize either of these payments. I have not shared my card or PIN information with anyone, and I did not give permission for these transactions. I have also not yet been able to contact Chime customer service about this situation. For reference, the last four digits of my Chime debit card are 5596. I request that Chime urgently review these two unauthorized transactions on my account and provide a full refund of both the $22.80 and $28.06 charges as soon as possible.
