Refund taking longer than 2 years

It is now more than two years and my refund is still not paid. The refund was was approved by both Travelstart and Kenya airways. I have all the emails and have tried to get an answer from Travelstart multiple times. They continuously ignore me and I’m hopeless. This is definitely corporate bulling. PLEASE assist me by calling me.

This is the only email I receive: Hi there,

Thank you for contacting Travelstart.

We apologize for the inconvenience caused to you for the delay in response due to high volume of queries.

Kindly note that we are following up with the airlines, will update you on the same.

Kind Regards, Refunds at Travlestart
