I've been with Vodafone before it was Vodafone. Used to swear by them but this last 10 years the service is .... poor to say the least.
I've been paying for a service I can hardly used due the sometimes non existing signal. I'm not in mountains or rural area but the 3 counties. I up grade my fone every two years. Just received notification of wifi calling... think it was new to Vodafone... seems not. Switched it on..... signal was worse than ever even cutting out signal to the point itsoon pointless making a call. Switched it off and can't remove it from my fone.
Really regret having to renew my contract but when a puppy chews your fone just before Xmas...
