Spam. You cannot call the number back either.

Had a call on my cell from this number. My blocker rejected the call and flagged it as 'Suspected Spam'. Judging by reports by other victims, this is definitely a spammer - reports on calls from this number include selling solar energy, installation of LED lighting etc. Caller is often reported as refusing to take 'no' for an answer and keep on calling even when told call recipients aren't interested. I seriously suggest callers report this number to Scamwatch, or at least don't answer and block this number. Whoever is making the calls is a real pest and deserves followed up by authorities with an order to 'cease and desist'.
