Shocking company, have made my son attend THREE appointments each time they had they had no record of the last. we have filled in and signed the forms twice and sent them in yet they apparently still don't have them. They have now taken to calling me daily to tell me the same information as the day before (They are still waiting for the forms to be returns and we need to bring him in for a medical appointment) We have told them that this has now gone on for 3 years and we can't be bothered anymore so please leave us alone, the car crash is a distant memory and my son is now fine, we don't want any compensation as it's not worth the hassle pf dealing with this company.
