Avoid at all cost!

First of all,i wish I had read the reviews on internet about Gotogate before I booked my flight. Booked a one way ticket thru Gotogate in march. The flight have been canceled due to COVID-19 pandemic situation. Since april i am trying to get a refund from Gotogate. This agency is catastrophic for the refund of flights and after aproximate 5 months of waiting i still havent received my refund. They do not answer to emails or phone calls either and i couldnt get in touch with them. More than that they also refused refused the chargeback. And AVOID THIS AGENCY AS MUCH AS YOU CAN!!
