Mytrip.com complaint: A complete waste of time!

I booked flights for myself a friend to travel from London Luton to Lisbon. When I completed the transaction I noticed I hadn’t received any ation email but the money had been taken from my bank. I contact Mytrip and was advised this is normal and that it could take up to 72 hours to receive the ation. So I waited patiently and three days later I receive a short email message to say they were not able to process the payment!! When I contacted the customer service number I waited ages to speak to someone and when they finally answered they could not have cared any less about what had happened. My experience seemed pretty normal to them. The only thing they could say is that they did not have the info sooner. What the actual fk!! Absolute scammers! I couldn’t even get any contact details from them to direct my complaint. I was told to instead check their website! How is this acceptable! How are they allowed to operate in this way! It is outrageous. Now I am left with no choice but to rebook the flights at a much higher price! A complete waste of time which I am having to pay extra for!
