Missed the call, called back and got a Chinese English voice talking about customer service. Typical scam call.

Caller: Marketing company

Nice enough guy, but just another marketing call from an overseas call centre.

spam

Did not take the call but when I called back they had a recording they what to connect you to a generic "Customer Service Team". Looks like a phishing scam.

I didn't recognise the number so I didn't answer. It didn't leave a message, which is typical of spammers.
