This number was unknown to me, but my phone recognised it as a spam call. The caller, who self-identified as being from Bikesure Insurance, left a 16 second message regarding the renewal of a motorbike policy, which I simply don't have. Could have been a trolling sales call, could have been a scam. Didn't reply, better just left.
