Honda Cars India Ltd. — its regarding crystal honda wagholi service center

Address:

Satara, Maharashtra

My car mh14bx8538 was serviced for 60k km service with the cost of 25000rs.
After that i drove my car hardly 2000kms suddenly i started getting engine heating up symbol after that i contacted rsa and they towed my car and sent to crystal honda wagholi and since last 12-15 days my car is there.
Initially on inspection there supervisor told me that in your coolant and engine oil got mixed and due to that it has happened but your engine is starting and car is running perfectly but still so we will drop off the engine and check is there any damage or not later he said just for precaution i will cylinder on lathe machine and said it's fine too.
Now today he has shared me quotation of 82000 rs and asking me these all parts we suggest to change and if you do not change them then there will be no assurance that engine will start or not.
They are doing cheat with us, i need immediate action on this. I am sharing the quotation images with this post.
