Email Hack - different email address

[Ajt8888]

Hi I am coming to the end of my contract and was offered a new deal via my online account, when I accepted the deal it said it was sending me an email but when I checked no email was received so I did the transaction again and realised that Virginmedia were sending it to an email that was very similar to mine but slightly different. I checked my online account and spoke to your sales team and my email address was the correct one I have always had in 15 years with Virginmedia. So where did this different email come from? It suggests a hack to me, and I would like it to be investigated by Virginmedia and my security in their system to be assured. 

[MOD EDIT: Subject title changed for clarity]

We're sorry to hear there was a slightly different variation to your email address. This is something we can certainly check for you but in order to do that I will need to confirm some information with you to pass security. 

I have sent you a direct message to allow us to do this with you in a private space. If you are using a PC/Laptop then you can just click on the little ✉ at the top right-hand side of the page to access your inbox.

Thanks,
