Eagle liner customer Services are refusing to assist me with a refund amount of R480.00. On the 01 August 2025 I paid to change the dates of 3 tickets i was then asked to pay an amount of R480.00 the amount paid did not reflect imediatley so i paid again and the amount reflected. The Tickets were changed i am howvever waiting for my refund amount of the second R480 paid. I sent the refund request on the 04 August 2025 till to date after emailing and whatsapp I still have not gotten my refund and have been told it takes 7 to 15 Days its past those days. ITS BEEN 20 Days now and no assistance.
