Started getting texts but no longer a customer

Hello,

I've seen this has happened to a few other people as well, but I have historically been a VM customer (not for a few years), and since leaving have periodically received texts from the same short code number that I used to when I was a customer.

They've often been in relation to network maintenance but today I've had two regarding precontract documents. 

I obviously want to make sure that nothing is being set up in my name, and I'm hoping it's just someone inputting the wrong number. 

Thanks 😊
