Yea, I've already passed it on to 3 people who are currently with VM paying a total of £45+ per month.
But they are either not talking to VM properly or the operator is not listening or playing ball by reducing their price even when the adverts being dropped through letter box's clearly state the £24 offer for Phone, BB and TV is also applicable to existing customers.
I used to pay £45+ PM, then after one phone call to VM they reduced it to £24 and also threw-in 24/7 free phone (calls and line rental for 01 & 02 numbers). The only other change to my service was a lower TV package.
