Getting texts saying I'm leaving virgin media but I'm not?

I don't know if this is just a mistake or scam but I'm getting kinda worried now. 

A few weeks back? I got a text from virgin media saying they are sorry I'm leaving and someone would call me to see if they could make me stay?

Issue is, I'm not leaving. I'm even under contract still so I don't know why I got this text? 

I put it down to a mistake or scam, but today I got another text saying I should have received my prepaid returns packaging?! And if I don't return their kit I will be charged? I've not received any returns packaging and don't want to, as again, I have no plans to leave virgin media. Not even looked into it so no idea where this is coming from?

I logged in to my account on virgin media and everything seems normal and active so I'm just very confused and worried right now.

Any advice would be appreciated.
