Shenzhen Airlines- in need of a bailout

I don't want to heap more coals but Shenzhen Airlines has done it again. I look the other way when small companies do things a little differently than I would do it but an airline company with personal vendettas against their customers!

Booked a flight to Shenzhen last week but had to adjust the return flight due to circumstances out of my control. I simply want to change from a Sunday flight on Shenzhen Airlines to a Monday flight on Shenzhen Airlines. I call my booking agency and they can't make the change because Shenzhen Airlines only allows Shenzhen Airlines to alter bookings once they are made. Fine. A phone number is given and I begin talking to the reps at Shenzhen Airlines. Turns out they, Shenzhen Airlines, don't have the ability to change flights either. Why? No particular reason. But turns out the only way to alter anything on a booked flight is to go directly to the Shenzhen Airline office at the airport????? I am sorry but I am not taking a taxi across the city to make a simple change on my booking which they would have charged me a few hundred RMB to have done anyways. But here's what I did do, I canceled my flight all together and booked a new one on Air China which despite the 84 RMB cancellation fee, ended up saving me 16 RMB because my new flight on Air China ended up being 100 RMB cheaper than my previous Shenzhen Airlines flight. I explained this to Shenzhen Airlines to give them a chance to keep my booking and redeem themselves. Not interested. Didn't bother them much that they were going to lose the entire booking to a competitor. Unfathomable.

You may be thinking why does he keep booking and dealing with Shenzhen Airlines. I may despise their tactics but when you have to fly often to Shenzhen and you fly on a budget then you are almost always going to choose the cheapest flight...which 99% of the time is Shenzhen Airlines. Believe me if I had another choice... I would take it.

Of course, my hand may be forced if I end up getting black listed.
