Had a call from 0208355xxxx saying there was a problem with my broadband which we would fix by downloading software from any desk.com. We checked internet speed on speed test.com which was 4.67 download and 16.3 upload but I refused to allow the anydesk access and hung up having told the caller this was a scam.
Was this the correct action? The caller had previously rung up last week but I did not progress past the initial conversation.
[MOD EDIT: number edited in case legit business number has been spoofed]
