On 6th October you requested I upload proof that I had 4 years NCD with my previous insurer. This I did by uploading my TESCO letter that clearly shows 4 years. I have now received a letter from yourself saying ' this information is in correct '. and you were charging an additional fee and premium. On contacting you today I was advised that in fact the follow up letter had been sent before you received my proof. I was unhappy with the tone of the letter and the fact I uploaded the proof on receipt of your request. I feel you follow up letter 'was just sent' without proper process.
