Hello again.
There is a positive outcome. Your colleague Nathalie helped me get a discount that allows me to keep the same bundle.
To be honest, I still don't 'get' the pricing of Virgin Media. According to Nathalie, the simple explanation is, the larger the bundle, the larger the potential discount. So in this case, had I chosen only Broadband, I would have received a reasonable discount for a limited time and thereafter would be charged the same price that I am paying now for Broadband, Phone, and TV. But because I decided to keep all services, she was able to apply a bigger discount. I suppose this logic will continue to confuse customers.
So, thanks to everyone who has offered advice and has encouraged me to get in touch with VM again. I must say that it is a good feeling to see loyalty being rewarded.
Cheers.
