Caller: Upgrade To Save

Received a call on my mobile from this number from a person calling herself "Daisy", with sub-continental accent (addressed me by name too but, I made out I didn't know who they were after and asked what the call was about and the company name). Claimed to be from company noted (checked on-line and could find no details!!) and call was to do with upgrade to a heat pump. I mentioned the number she called was on the DO NOT CALL REGISTER and that I'd now report the call ... then she promptly hung up so, deduce this was a scam as well as a nuisance call

Did not recognize number, did not answer, no message left. Rang back recorded message " The number you have called is currently unavailable". Suspect a scam. Blocked.
