Vodafail might be happy with their network
But far, far too many people have put up with their shitty service, and shittier customer service where they attempted to blame their own customers for owning "incompatible" handsets, which Vodafail sold to them in the first place.
I had 10 years of good service with them, followed by 2 year of very fucking poor service that required intervention of the Telecommunications Industry Ombudsman to sort out. The fact that the TIO was investigating the matter still didnt stop Vodafail from hiring Debt Collectors to chase me down for money I refused to pay for shithouse service. Their attempt to coerce payment from me by threatening my credit rating only served to get the TIO to come down on them even harder than they were going to initially.
If they were willing to treat a loyal customer that way, theres no fucking way in hell theyre going to get my custom ever again. It'll take the simultaneous meltdown of both Telstra and Optus's networks for that to occur, and even then, I'll consider getting a Sat-phone before going to Voda.
