Rejected claim

What a horrible insurance company, 5 months ago we were called to take up the insurance, no follow up was done as to weather the cars were taken for inspection or not then I had an accident they rejected my claim cause there was no Inspection certificate. They even took out my car out of the insurance but they continued debiting my husband even though the paper work was not complete I mean surely after 3 months they should have seen that there was no inspection done and reject it then but no they continued debiting us still. Stay away from this insurance.
