Poor service and misled promises on Warranty Claims

Logged a motor warranty claim on 8 december and after 3 sets of assessors failed to pitch up for repair assessments now 20 dec 2021 , i am without a vehicle as well as i am sent in circles to rent a vehicle covered in my policy(25 calls made and most cut off). Promises are made to contact me with feedback and nothing is done. Seriously poor service from Nedbank and insurance departments linked to Nedbank. Maybe contacting the ombud is best.
