Major Damage to Engine - Very Dishonest!!!

i took my car in for a timing chain replacement… when i got it back, the car wouldn't idle and kept stalling. Leeto told me this was normal and i must drive it and give it time to fix itself. I took it somewhere else the following day to be checked and Leeto from Motor flux had replaced the timing chain incorrectly and bent the valves. Sitting with a major engine damage and bill to repair, Leeto wont take my calls and is always busy. he does not respond to my messages and has blocked me on WhatsApp. The day i booked my car in at Motorflux, there was an angry women shouting outside their workshop, saying they stole parts from her car and damaged her motor. Leeto said she was a not right in the head and joked about it. I wish i had listened to my heart and walked out that day taking my car somewhere else. The lady at Motorflux called Susan threatens you and Leeto ignores you.
