CHERY TIGGO - help repair

The problem is this: two months ago, the car stopped starting on the first try in the morning — you have to crank the starter about ten times. But once the engine catches, it starts like new all day. It's been at the service center for two months now, and they keep feeding me promises. They replaced the pump, the return line, flushed the injector, even wiped the headlights — and no result. I'm just furious.
