Hi John19701 👋 welcome to the community! Thank you for posting.
Sorry to hear about your concerns regarding these calls! We would need to send you a PM to confirm a few account details so we can check if the calls are legitimately coming from us. In the meantime you can also find more information about dealing with nuisance calls 👉 Dealing with Fraudulent Calls & Vishing Scams | Virgin Media Help and you can also update your marketing preferences via your My VM account here 👉 virg.in/myVM.
You can find my PM in the top right corner of the page in your Inbox. Thank you for your patience whilst we investigate and get things sorted! We can return to this public thread with another update when possible.
All the best. 🌞
