This is why I grit my teeth every time I see people on these forums recommend a travel agent to prevent problems, they forget that many of the local travel agents are not that good. Here this travel agent couldn't even handle a simple reservation of booking a Comfort+ seat, instead it appears that the TA booked a std economy seat and then paid a seat selection fee. This is not what was asked for. What they were missing in what was chosen was The Early Boarding, Guaranteed Overhead space, a Big Selection of Snacks, Free drinks. All they got for their money was a seat that could be revoked by a gate agent or FA at their discretion and would have been forced to sit in a std economy seat without the legroom they had paid for.
