One of my drivers recently crashed one of the zafiras. Aviva kept telling me for two weeks it was being repaired but then decided to write it off so went out and bought a new one to replace it. Phoned brokers (Swinton ) and gave them all the details to swap the vehicles over on the policy two days later
a certificate arrived BUT despite the fact that all my vehicles on the policy are hackney they have taken the written on one off and put the new one on as private hire

so phoned them up and was promised a new correct certificate by email.
Nothing has arrived and apparently there is a problem as Aviva are insisting it is a PH vehicle not a Hackney even though it was a replacement for a hackney so the question is
what is the best form of legal action to sort this out has anyone been in this position before ?
