I booked my car hire last week via airline network following an email sent to me entitled 'don't be an april fool'. The contents told me to book a full size 4 door and get upgraded to a minivan, we always book a minivan, although there is only 4 of us DH, myself and eldest DS are over 6 foot tall so its just more comfortable. So online I go and try to book the 4 door full size (including platnum upgrade), it even tells me again that if I book a FDAR i get upgraded to MVAR, but alas it came up with a problem processing my debit car, later that morning I rang them and paid the £424 with no problems. At the end of the conversation and after I had paid I just confirmed the upgrade as no mention had been made, and the girl knew nothing about it, so she put me through to customers services and a nice chap called Darren, who knew nothing about the promotion but changed my booking upgrading me to a minivan and giving me a new ref. no - great I thought all read. Yesterday I recieved a letter from them asking me for another £34 to complete my booking, no explanation as to what the extra money was for I rang them, the girl that answerred had no way of telling me what it was for just that I had to pay it and if I didn't they would not issue me with a voucher. I aksed to speak to Darren, and in the end I ask if he can phone me back - 20 mins or so later he does telling me that I had misread the email and that what they had done was that they had reduced the price of the minivan to the price of a 4door full size, not what my email read at all and I asked him to wait whilst I logged on and read it out to him. He was now very confused as his superiors were telling him totally different and I have now forwarded a copy of the original email to him. As all the bosses had gone home when he phoned me back last night I am now awaiting a phone call this morning - I refuse point blank to pay any more money as I read the email correctly and booked what I should do but did not get the promised FREE upgrade - so beware if you are booking this April deal don't be taken for a fool. I will update you when I hear more.
