Caller: Not sure

Someone wanting to talk about hot water systems, I missed a call, called back and got straight through to someone, when they said what it was about I said not interested Thankyou and hung up. I then received a phone call back straight away demanding I at least listen to what they have to say so I hung up and blocked number.

FLAGGED AS SPAM....declined call & blocked number
