Hyundai The Glen unprofessional.

I am very disappointed with Hyundai the Glen. My husband took my car in on Monday 02/03/2026 for some noises we didn't understand. The car was booked in prior. The was no update from the workshop the whole day Monday. Only the windscreen people phoned to make me aware of the windscreen chip. The dealership phoned my husband an hour before the dealership closes he was already close to the dealership. He was told they didn't find any problem when they checked what was reported on the car. They suggested he leaves the car at the dealership overnight they will check it on Tuesday. Then Tuesday he was told they suspect cambelt and timing issues when he was already at the dealership late afternoon , no update the whole day. Car left there to be further inspected by the workshop. Wednesday afternoon i phone to get an update on the car and i told them the car is mine. I spoke to four people before i could speak to a mechanic. I was frustrated and he told me he only started working on the car on Tuesday. My husband decided to collect the car on Wednesday because of their unprofessionalism. And he was slapped with an invoice of R80k. He says the mechanic drove and parked the car from the workshop asked him if he can hear any sounds from the car and advised my husband to buy oil for the car, the car is from service at the same dealership about six months ago. Today it's a Thursday the car was collected yesterday from Hyundai The Glen, there is a new sound from the gear lever. What happened to the car now. Seems they are using *********** mechanics. From no problem found to R80k invoice with a bonus of a new abnormal sound on the car. Hyundai the Glen how did we get to R80k when initially there was no problem found. Your mechanic should explain why he asked my husband upon collecting the car if he can hear any funny sound, did he fiddle with the car not knowing what to do. Did he cause more damage to the car. We want an explanation, not at 16H00 when it's an hour before the dealership closes.
