Phoned and did not leave a message. I do not know this number!

I got a call from this mobile, they hung up as soon as I answered. I tried to call back and the recorded message said, thank you for contacting customer service team. We are happy to assist you today, press 1 to speak to the next available agent, press 2 to leave a message, press 3 to opt out. Did not say the name of the organisation so I do not know who I was contacting and as I googled the number, it is not reporting any busyness attached to it. I believe this to be a scam of a way to spoof my phone by attempting to engage me. BLOCKED the number, definitely a scam.

left a message just sounded like a call center in the background ?? went for 1 minute, it come up as suspected spam

Called and when answered hung up then when called back number was unavailable from my service provider.

No message and unable to call back ?? Blocked !!!
