Dreadful experience which echoes that of other reviews. Over £2.5k of long distance flights cancelled by Malaysia Airlines but only offered vouchers by Opodo, with whom I booked the trip. Tried to reach them but they don't answer phones or provide an email contact. Spoke to Malaysian Airlines who confirmed a refund should be issued by Opodo, they even contacted them directly and provided an email address to forward an email confirming the same. Opodo's automated reply received to say I gave to take it up with the airline and may have to wait up to 3 months!! Shocking! They should not be allowed to operate...don't make the same mistake I made.
