I had a similar experience in January, but I held on and negotiated a discount. However, my discount hasn't appeared on my bill, so I raised a complaint, only to find that my complaint has been deleted! I used to think VM customer service was ok...now I've completely changed my mind. It's diabolical!
Thank you for reaching out to us in our community and welcome back, I can see your original query was in regards to your price going up by £22.00, after having a look our end it looks like this may have been due to your current offer ending in the period the bill covered, I can also see that you have since spoken to us.
Did you manage to get this resolved? I appreciate you tried to call on a couple of occasions and didn't manage at that point, apologies for any inconvenience caused.
