I've been trying for weeks now to upgrade my wife's SIM only Vodafone contract. I'd like to order the 4GB Red bundle which should include: 4GB UK data Unlimited UK minutes Unlimited UK texts 2GB of roaming data Unlimited roaming text and minutes Normally this would cost £22pm, however I can get Vodafone's Advantage discount on this of 20% taking the cost to £17.60pm, also going through Quidco should see me getting £60 cash back (though that is based on a per monthly cost of £22 which with the discount it wouldn't be, but should be £50 cash back at least, as this is what you get for £12pm or £15pm SIM only contracts. I won't bore you all with the webchat transcripts as they are a joke, but basically I've not been able to get this processed for 2 weeks now.. The first time I tried their site kept crashing, or I was getting 404 page errors on two different PCs and using Explorer and Chrome. When I did eventually get the order placed 2 weeks ago I then received this on a email: So the first webchat was asking how they got from £17.60 to £19.07 + VAT taking the total costs back to £22pm? I was told this was sorted out after a 45 minute webchat, however I noticed the contract 2 weeks later is still the old one, so this didn't happen??? So I try again today.. This time firstly their site wouldn't allow me to add the Vodafone Advantage discount saying it was not allowed on this deal, that is despite the site saying it was allowed on all 12 month SIM only deals. Then I try it again in another PC which this time after one 404 error seemed to work, but I didn't have to enter the advantage discount code, it had just added a "Vodafone Discount" of 20% instead, great I thought... However! When I clicked through to the summary page, I noticed that the details of the contract had changed to 3GB of UK data and 1GB of roaming data. How is that even legal?? I clicked on the 4GB bundle and had I not noticed it had changed in the summary I would purchased it: This then started off another 50 minute webchat where they offered to process the upgrade on their internal systems, but that is no good to me as the Quidco cash back would not track. They wouldn't answer why the 4GB contract turned into a 3GB contact without any warning until I really pushed it and then they tried to say they can't control 3rd party sites (basically blaming Quidco) I said I'm not on a third party site I'm on yours! I've just been directed to you via them, so never did get a proper answer to that... Anyway, apologies for the long rant, ended up asking for PAC and now on the hunt for a better deal as I've had enough of them and even threatened to invoice them for my wasted time. LOL! Anyone else had similar issues or noticed this 4GB contract turning into a 3GB contract without any warning? Surely that is not legal? Thanks.
