Ok - The free netbook and 3G dongle I can understand, but why on earth would you think they would pay for your monthly data usage too? 3g ain't cheap and no business on earth would offer to give all that away for free without a very good reason (which I'm failing to see from your thread).
Ok, if you want the fullish story behind the FREE bit then here it is.
When i initally called the sales team i asked "what extra charges am i going to incur" and i was told "no extra charge". I asked this question several times and again was told the same thing. Towards the end of the ordering process the agent tells me "there will be a £15 per month charge for the dongle" To this i relpy "i am now confused as i have asked several times how much extra is this going to cost me per month on top of my current package and you told me nothng", she appologises. I tell the agent that i no longer want to proceed as i already pay on average £100 for my VIP package and i dont want to pay anymore thats why i asked several times "how much more per month is this going to cost me". I also said "if anything i should get the dongle for free (long shot) due to the amount i currently pay monthly" The agent said she would have to speak to her supervisor and put me on hold - when she came back she said "you can have it for free", i replied " i can have the dongle for free and that means no monthly fee of £15pm" she replied "yes"
So as you can see i was told i could have it for free. I did however have to re-enter into a 24month contract for the rest of my services.
PhillyDee - i didnt scam them in anyway. I went in blind as to what the package of the Netbook inluded. I saw the advert on their website "FREE NETBOOK". I asked the question to the sales agent of what extra it will cost me to be told nothing. Once i found out there would be a charge i told her i didnt want to proceed and merely suggested i should get the 3gb dongle for free at no monthly charge - she got the free dongle at no monthly charged authorised by her supervisor.
All ive tried to do since was to get the deal i was told i could have
It hasnt been as simple as it sounds, it took 15days to get the netbook delivered, i had two failed deliveries both their fault. I had spoken to at least 15 agents and spent around 6hours on the phone. I had numerous failed call backs. I spent 80mins on solid hold on one occasion only to be cut off after a futher 20mins and then having to call back an do it all again.
When i logged the complaint via the newsgroup (8 weeks ago) all i was getting told was that it had been passed to their manager, this was to be their weekly response everytime i requested an update - this brings me to today when i had fanally had enough and i emailed the CEO.
You ring them up and ask for a better deal than you originally wanted, you usually get it off VM.
