Car Parking Refund from Ryanair after they have cancelled a flight

FishFace1

I made a car parking booking via Ryanair at the same time that I booked my flights with them from Manchester Airport. A couple of weeks later Ryanair cancelled the return flight, so we had to rebook our return flights for a day earlier, as they had no seat availability on the original return date. Because the initial car parking was Meet and Greet, I requested for Ryanair to amend the original car parking booking arrival date to reflect the new flight return date.

The representative on chat said that the date could not be altered, but they would cancel my car parking booking and issue a refund within a few days. I then made alternative arrangements for car parking through another company.

Several weeks elapsed after returning from holiday and the refund had not been received. I contacted Ryanair customer services who said that because the car parking was with a third party, they could not issue a refund. Instead they sent me a link to Manchester Airport Car Parking.

However on the Manchester Airport Information that Ryanair sent to me it states ""Please note that your booking is non-cancellable. In the case of a flight cancellation or schedule change, please contact Ryanair customer service. For all other queries please contact Manchester Airport Group." 

I have also phoned the Manchester Airport number on the link and they said that Ryanair should be processing the refund. 

Has anyone else experienced a similar situation and managed to obtain a refund?
