This number called, I let it ring out to go to voicemail. No voicemail left. Called them back, it went to an answering machine that didn't announce who they were, simply "please hold while we try to connect you". Didnt stick around on the call as it felt very much like a scam. I note a similar number beginning with 07 2139 is absolutely littered with scammy robot debt calls claiming people have debts from eBay, which is just not a thing. I suspect they have a series of phone numbers starting off with 07 2139 and are trying to con more people. Blocked the number. Suss.
