Extremely Disappointed Customer

This Company is extremely unprofessional, not organized and it's overpricing everything. I took my 2014 Chevrolet Cruze Sedan to them on December 2023. The car overheated the problem is the engine. Still in December I asked the owner Mr Ivan via whatsapp how long will I wait for the car roughly so that I can plan for it he never rep****. I went to them on January 2024 & found that the car was still the same they haven't started working on it. Now only after I went to them and complained that's when they claimed from my Warranty Innovation Group on 18/01/2024. They told me to open the engine is 5k and to close it it's another 5k without fixing anything that is just for diagnostic purposes 😲. Innovation Group approved my claim on 26/01/2024 and emailed it to me same day. Approved amount was 40k, BLACKHEATH AUTO SERVICE AND REPAIRS never get back to me until I contacted them on 09/02/2024, they said they forgot to get back to me and give me the Quotation they then told me via phone call that their Quotation is 90k/ R90000 for fixing overheated car imagine, this simple means I must pay them 100k/ 100000 😲. I never received any official quotation document/ letter from them detailing everything. My car has-been there for 3 months now & they've started fixing it. These people have no sympathy and they don't value their Customers. I told them I'm using that Car everyday because I stay in a very isolated area there's no public transport at all there I'm very stressed because I'm using Uber to go to work everyday and that costs me money angry 😡😠😡
