Stick to your guns, you are the customer, and ebike should recognise this.
Its prob cos they have deals with 'authorised' repairers, who they already pay direct for work done.
If RC do accident repair work for any insurer then this will help your case.
Check with trading standards if you have to, if this 'request' is within the law.
Afterall, if you had a bashed Harley, you wouldnt expect it to go to a Kwak dealer for repair and vice versa. Neither would you expect to take a bike/car to a non-qualified (in that marque) mechanic/dealer for repair.
Good luck
