GROUPON AIRPORT VOUCHER IS A CON! I purchased “Looking4Parking” Groupon voucher worth of £4 which said it will be up to 35% discount. Instruction on Groupon was not clear or concise, it just said to put Groupon code while booking. The only option to enter the code was at the beginning, before you pressed the compare button, which I did but no discount was shown. Even more the price with the Groupon voucher was £76.95 when if I would book without voucher it would cost only £67.72 which is £9.23 more. At that time I presumed that discount would be deducted at the end so I carried on with booking. However it never did. I phoned Groupon and I was told that I need to bring printed voucher on arrival to the company and will get discount refund. I phoned the company for confirmation but was informed that Groupon provided me with false information as no refund will be given. Also they confirmed that my booking is not discounted and I can not change or cancel it due to the type of booking. They said they can not help me here and advised to contact Groupon and solve the problem with them since I bought the voucher from Groupon. However when I contacted Groupon they advised me to talk to “looking4Parking” to sort out the issue and get refund of any surcharge from them as they would not going to pay back any difference that I lost using my Groupon voucher, even though it is Groupon who advertise that they have contract with the company on their site and they should take responsibility when something there is a problem. Groupon absolves itself of responsibility by throwing problems back at their loyal customers. Groupon just misleads customers and deliberately conceals the full information which leads the customers to believe it is a good deal when in reality it is just a con. I am very disappointed with Groupon services and "deals?" luckily it is not a large amount that I have lost, though stop using Groupon in the future. I am relieved that I realised what a shady company Groupon is before investing into a more expensive deal.
