2011 c70 oil leak

[Rey464]

Hi all, so I’ve taken my c70 to the repair shop to fix an oil leak among other things ie timing belt loose and causing hard start/ engine timing/ P016/17 issues. The shop discovered the tbelt was replaced but not the tensioner, they replaced including the water pump and also replaced an oil seal around or near the oil pump. The car was fine after that but within a month the oil leak was back, I took the car in again and they said the seal was not placed correctly so they did it again, about a month later again it’s leaking, im going to take it in again for the 3rd time. Can anyone relate to this and advise me ? Thanks.
