Bala poor work done by TASS. I would suggest you to call fiat RSA helpline 1800-209-3428. Also file a complaint against your TASS at Fiat service helpline and email id firstname.lastname@example.org Engine oil leaking is a serious problem. If engine gets starved of engine oil due to excessive leakage the engine of the car will get seized due to overheating. If you still want to drive it to TASS take a extra bottle of engine oil with you and keep checking the engine oil level at regular intervals and topup as necessary.
