A little story. I took out a case with The Motor Ombudsman (TMO) and last week I was finally repaid by the garage I raised a case against. The culmination of 2 years!

Whilst TMO found in my favour (twice! ... explained later) I would struggle to recommend this route for anyone pursuing a decent sized claim or looking for a quick recovery. TMO are woefully inefficient and the garage/dealer was not just slow but also just stopped communicating with them as soon as it was initially found in my favour. It became more a pursuit of curiosity and amusement so, when I remembered, I would chase TMO for an update which, when I did get a reply, just kept moving out with their estimation date.
I initially received the finding in my favour after just over a year from raising. The garage then didn't pay me and stopped all communication with TMO. TMO gave them a long time and many chances - too many imo - but still nothing and eventually I was told it had to go to an Ombudsman (this confused me as that's where I thought I was, but apparently initial finding is by an Adjudicator, not an Ombudsman) so the process effectively starts again from scratch. It needs the 2nd review by an Ombudsman so that if the garage don't comply again they can then escalate to their compliance area

If anyone else is thinking of going down the route of the TMO I've probably learned a few things along my journey. To be fair, they got there in the end and their two findings reports were quite detailed and well summarised. It was for a sum I was barely interested in so really feel for those with cases that might run to many £k's if my simple little case was dragged over 2 years.
