Virgin saying they haven’t received equipment I returned over a month ago

My daughter returned virgin media equipment sent to me in error; I think she entered my email address incorrectly because I haven’t received any confirmation email etc from Virgin etc to say it’s been returned successfully / I’ve just received a text to say I’m being charged £65

surely virgin not receiving the equipment lies with them? I know I don’t have proof of return because my email address has evidently been entered incorrectly.

im not sure what to do. I’m a 70 year old vulnerable lady. I’ve been severely unwell the past few weeks and virgin want to charge me this close to Christmas !
