Your clutch thrust bearing has collapsed. This is why it's hard to get into gear. This is why your car creeps when in gear even with the clutch pedal down. This is why it'll go in to gear easily when the engine is not running, and the car jumps if you try and start it in gear.
How many more ways do I need to prove it to you? No, I'm not a car mechanic, but I've changed clutches before, and have rebuilt a kit car, including the clutch. No disrespect, but your skills are not mechanical. When I need accounts advise I listen to you. You moan about you car, and then tell me I'm wrong...
Then, why ******* ask me? Is it just the quote you got from the main dealer for replacement? I admire your ability to keep the costs down, but sometimes you've gotta payout..
Ohh, buy the way, if you buy cheep, you get cheep. This is why I drive named brand cars. Dacia? Sheesh. Like Kia was 10 years ago, but without the quality control.
