Scam/Fraud
42 minutes ago
I got a call today but the line was terrible. They might have been from 3 and seemed to be calling regarding poor network service. I confirmed I had not experienced network problems. They started speaking about providing me with some sort of offer in regards to this which raised alarm bells. They didn't mention my name and didn't confirm any details with me, which led me to believe this was a scam call. When I said I was happy not to recieve any offer they hung up without any further discussion.
