Getaroom.com exorbitant fees TX Dallas

On 08Jun2021 I made a reservation on what I believed was the Hampton Inn website. Somehow GETAROOM.com hijacked my session (res #R2578256078). The rate for 11-13June was $442.48. I hit the reservation button and received a text from AMEX stating GETAROOM.com charged me $626.31 including a $183.93 “Processing Fee” that I wasn’t aware of.  I immediately called and asked to cancel since I did not agree to the exorbitant fees (it had been less that 2 minutes).  They refused to cancel stating it was non-refundable. I pushed Jason to please help me, he finally agreed to a 10% ($62.63) discount.  Unsatisfied and feeling totally scammed I called back and escalated to a Supervisor (Jaylen N).  He refused to cancel and agreed to a 15% discount ($93.95). These fees are exorbitant. The massive list of BBB complaints shows most consumers agree (1,106 complaints closed in last 3 years).  They are rated as a “D+” and BBB determined the allegations, and overall concerning pattern of complaints, persist. I would like GETAROOM.com to provide the balance of the $183.93 “Processing Fee” ($89.98) as a refund to my AMEX immediately.
