Gotogate - Gotogate flight ticket cancellation for refund

I booked a flight by Sri Lankan airlines for Dubai from Chennai via Colombo using Gotogate for ** th November. I was later informed by the Srilankan airlines that Indians are not allowed to travel to Dubai via Colombo due to some agreement due to COVID **. Therefore I requested gotogate for a full refund for which they have been constantly neglecting to provide a proper solution. Each and every call with the customer care agent is a headache where each person says a totally different story. I however did manage to talk to Srilankan airlines and got a positive reply from them stating that a full refund is possible for booking W*NM**, however the gotogate has been constantly avoiding my calls and only seeking a way to end the call rather than to provide a solution. It has been more than **-** days and I am still following on the same with the Srilankan airlines and gotogate. There is only * more days and they are no where near to providing me with a full refund. I sincerely regret using gotogate and would never recommend it to anyone in the future. They have a horrible customer service and have no respect for their customers and zero respect for their time and hard earned money. Even after the Srilankan airlines have accepted to provide a full refund they do not want to proceed with the same.
