Mango Sardine Tin - Poor Feedback

I sent a complaint to Mango Customer Care on 1st of August with a promise of a 48 hour turnaround. I received no response. I resent it on the 14th, & still no feedback. I flew Mango JE288 on the 1st of August 2018 in Seat 23C. While I may be considered relatively tall at 6'1", the leg room that I had in this seat was no more than a hand's length to the seat in front of me. (Seat 23C). While I am all for optimizing space to achieve economies of scale & make flying affordable, it should not be to the extreme discomfort of passengers. Incidentally I flew back on the same plane in another seat, & while it also had had thin legroom, it was considerably more than Seat 23C.

Mango, your customer service & feedback is very poor.
