Canara Bank — Regarding my car loan

Address:

mohali

I bought Innova crysta and financed some amount from Canara bank kharar Mohali branch on 20th June 2022.
Canara bank employe Jyoti promised me same day loan and car delivery.Jyoti mam said sanction amount is 14lacs and other pending amount I paid to Toyota company.I repeatedly message her and call her for my sanction letter but she refused and said sanction letter comes after one week time. Now Globe Toyota Mohali told me that they only received 13lacs from Canara bank.I said my loan is of 14lacs not 13 lacs.Moreover Jyoti mam called me and said your Cibil is low only 13 lacs approved.i told her why are you telling this after 2 months and how I can arrange funds right now and I request her to send sanction letter to email id. When I read the sanction letter its totally against the communication between Jyoti mam and me.
Moreover
(1)date on sanction letter is 28/06/2022 which is 8 days after the car delivery.
(2)Interest rate shown is 9.7% which is far more than committed 7.35% and overwriting on interest amount.
(3)Without the intimate she add my family member as co-obligant in loan.

Now she said due to your Cibil score your interest is high otherwise your loan can not process, and they said you have to pay one lakh remaining amount to dealer because we can't finance 14lacs.

I am doing job I can't pay high interest rate and I don't have extra money which is one lakh.Which I can't pay right now to dealer.
Kindly help me out and decrease the interest percentage and disburse full amount to dealer.
