Eldo will never refund

I had to postpone tickets, could reschedule because all Eldo busses for my selected dates were booked. I submitted my refund request with all required documents on the 18th of December and received an email stating that it will take 7 to 21 working days. After numerous dropped calls and unanswered emails today I was told by an hosest employee I am number 734 in line... I have been every excuse in the book, accountants on leave, accounts sick ect. After reading the reviews regarding other unpaid refunds I realise that all they will do is refer me to another person or send another email. This is a company with a 734 refund request backlog, I would thing they could afford to hire more a accountants.
