I was a customer of Vodafone continuously for over 18 years , at first when the network was 100% Ericsson it was clearly the best network, it work everywhere i went and worked well. Since they started installing non Ericsson equipment in the last 5 to 7 years the quality fell, due to giving contracts to the lowest bidder. having spent most of my life in communications it is well known that there is some equipment out there that just does not communicate with others on a signalling level and therein lies the problem, you have to introduce interface equipmet that translates signals, introducing delays. The last three or four years the network became so hopeless and my bills grew so big that i had prepaid accounts on other telco providers to reduce costs, i was solidly loyal to vodafone in spite of this. in 2009 when my most recent contract fell due i was offered a new phone and new plan and because i had so many problems i extracted a verbal guarantee from the telephone salesperson that the problems were over if i took the new handset or i could cancel my contract. two days with the new phone and nothing had changed so i called in the promise, i got several new handsets sent to me over three weeks proposing to solve the problem but in the end they had to honour the agreement and cancel my contract. i moved to telstra and service was vastly differnt, it took vodafone 7 months to send me a refund cheque after calling them week in week out for my refund, alas i read they have bought huawei equipment, all i can say is good luck vodafone you made your bed now lie in it.
