ONLINE CHECK IN FOR NOTHING

It has now been 8 days since I've sent an email to Mango airlines and i'm still waiting on a reply.<br> <br> I booked a seat online 2A - window seat and when Mr de Souza (traveller) arrived at the airport with his boarding pass he was told that he would be seated in 5 E - middle seat squashed between two passengers. <br> <br> We always check in online to avoid this scenario and to allow for some room so that you're not squashed in the middle.<br> <br> Mango couldn't give him a reason for the change and we also weren't made aware of this.<br> This is unacceptable<br> At the airport they weren't very helpful and merely told him that this would be his seat and that there's nothing they can do!!! <br> Why even bother allowing passengers to check in online if this is the case?????<br> <br> I would appreciate a response at least. Not only did we get bad service at the airport from the unhelpful check in assistant, but their online queries department is also avoiding the issue. <br> <br> <br> <br>
