Complaint Review: Wizda Service Center

I instructed Wizda to not perform any major work on the car, except for a standard computer diagnostic check in order to find my car's problem, without first giving me a written estimate that included the following:
1. It should identify the condition to be repaired, the parts needed, and the anticipated labor charge.
The written copy had to be signed by Wizda and myself. Wizda's did not provide me a written estimate. Instead, they a) Misdiagnosed and b) performed unauthorized work on my car. The car's problem was not mechanical for which they charged me $1000 when a new fule pump at the Nissan's dealer costs less than $250. The problem was electrical which was found by Nissan dealer where i took my car after Wizda's owner lied and the car died on me again. do not take your car there.
