Poor service and lack of response

I am absolutely shocked & disappointed that Dotsure's processing of my claims is so poor. I submitted 2 claims on 4th of October which are obviously urgent. I submitted ALL the required documents on the 4th and since then all I have received are constant sms's and emails about submitting the necessary documents, saying that if I haven't done so by the 11th of October, the claim will be cancelled. I have phoned them, I have emailed them, I have chatted to their consultant on the web, I have left a message at the call centre, I have held on for over 25 minutes and I have still had no response. This is exactly the same process that happened in March when I put a claim in for my gearbox - they kept on saying they hadn't received my documents despite me having sent them through a number of times. This is obviously a delay tactic and I'm not going to recommend them to anyone else again. This is a disgrace.
