As soon as they mentioned HMRC refund I ditched the call and looked up the number and it was a known scam number. If it doesn't stop I'm switching providers. SCAM CALLS ever since moving to O2 network!!! In all my many many years of owning a mobile phone, I've been very careful with my phone number and I've NEVER had any SCAM calls. The very DAY, we were sold off to O2 I start to get SCAM calls from Manchester pretty much every other day from a Manchester number. Coincidence? 😡 Solved
