I have gotten many calls from telephone number 01156920000 and when I answered the callers said that I was involved in a traffic accident, which I never been in. The callers also told gave me a company name which I have never heard of, so asked him for more details about it and what car I was driving just to see his response. But, the callers started getting really angry for some reason and then hung up. I then blocked 01156920000.
