Poor Servive

I am hoping that through this i will get a response from Mango...<br> I made a booking through the app and payed for the flights at a checkers hyper to only find out once the transaction was completed that seats cannot be chosen. <br> I have been trying for about 3 hours which is totally unacceptable to try and make sure that the seats for my wife and I are together and to inform Mango that she is also pregnant so an ile seat would be great near a toilet if possible but no response. I have also sent a mail to [Email Removed] to which there has also been no response. <br> Poor service from Mango and I am slightly disappointed.<br> <br> Mango's terms and conditions state that when booking at checker hyper kiosks a fee will be charged extra but no joy.<br> <br> Please can I get a response asap or else this transaction should be cancelled and I'll find flights elsewhere.
