Just had another call from this number. Asked them to tell me a bit about their company, whether it was a Ltd entity or a PLC. He didn't know what I was on about and I asked how he didn't know more about the company he was working for. Transferred me to a colleague who was also confused. Then he told me he was having trouble breathing and needed to go. I told him to visit Occupational Health.
27/Sept/18: Asian gent said I had a problem with my PC when using the Internet. I told him he was just a scammer and how does he live with himself each day earning a living doing that. He began arguing saying he was an Engineer so I hung-up.
