On Friday, December 1st, 2023. My husband purchased a round trip ticket for me, from Gol Linhas Areas from ***** to Braslia for the amount of USD *******, after taxes and fees. In the meanwhile, I got sick with pneumonia and couldnt fly, canceled tickets on December 21st. The flight dates would be December 23rd, come back on January 5th. According to my receipt the trip had a different fare for each way. On the way to Braslia it was supposed to be plus and on the way back to ***** a premium. Looking at cancelation policies on their website, each one of the fare categories has a different amount for reimbursement. ****************************************************** The next day we got a reimbursement of $529.90. But given it was two different fares, the amount reimbursed didnt seem fair. Their customer service was not helpful, as the number for US customers they didnt know how to explain anything. Had me calling 2 different numbers in ****** to see if I could get an answer. I spent 5 hours on the phone to get a resolution.When asking about how they came up with this amount, they finally explained that the system calculated it all as the lowest fare plus for the entire ticket. I would like to see what justification they have for this, if there were 2 different ticket fares. Why did they apply the lowest one to the entire amount? Personally, they didnt want to go any further into this, leaving me with a lot of questions. And no ability to complain to any supervisor or any other department.The ticket price for the trip ******* was $458 (plus fare). The way back BSB-*** was $945 (premium fare).Not sure, if my calculations would be completely on point. But I thought I would get something like $1004.55.
