Update to original review below: since the original review, One Call have reached out to me to better understand the issues raised and provide me with contact information should I need it in the future. Having been sent a email threatening me with debt recovery, on contacting One Call, it turned out to be their error. It was incredibly hard to find the live chat window with which to contact them, there are no phone numbers posted on the website and all emails are from a "no reply". The debt I was emailed about had never previously been brought to my attention and One Call should have checked the apparent discrepancy properly before sending out "worrying" missives. The person I contacted on the live chat was very helpful and resolved the matter in about 5 minutes, however, the only evidence I could get was by emailing the chat contents to myself and I was subjected to unwanted salespersonship - trying to get me to upgrade my insurance package.
