Roojai Customer Services Poor Response

Does anybody have a contact for a Customer Services Manager at Roojai insurance? Not the 'first contact' customer services but a step up from there.

Three weeks ago I renewed my car insurance with Roojai for the 6th. time. For every one of those renewals, until now, I've had maximum 50% No Claims Bonus. This time, NCB was REDUCED to 40% with no claims or changes in circumstances.

I immediately contacted Roojai customer services and asked why. Their response was that they'd urgently contact the underwriting dept. for an answer.

No answer so far despite a reminder - so not very 'urgently' - and I want to take it further.

TBH, despite their claims to have 'Award-winning customer services', I've always found them pretty useless for anything other than routine, mundane questions. This hasn't improved my opinion.
