Re: Whatever ....
I've been with Voda for 10 years since leaving the former Orange. Orange CS truly was (shit)^2 and that's why I left them as a customer of 10 years (since the Hans Snook days).
I've not had many problems with Voda (but I don't doubt others have). The online chat resolved an overbilling issue - it took a while but I just did it in the background while working on something else (probably like the agent was doing). The Level 2 support in Egypt got Wifi Calling working during the Christmas break last year and even called back as promised while also being friendly and helpful.
With no disrespect intended to either those Voda staff who are trying their best nor the people who have had shitty service from them and hate them with a passion, I'd put them down as the "best" of a truly bad bunch:
EE: Terrible before acquisition by the utterly dreadful BT
Royston Vasey Three: You'll never leave (as we don't give out PACs)
O2: Crapita (Enough said)
