Terrible Service - Auto Aircon (Eastleigh, Edenvale)

Terrible service at Auto Aircon (Edenvale). Took in an Audi A4 A/C compressor for recon, had it removed from vehicle at Bosch Service Centre (Edenvale) as Auto Aircon labour rate is R950/hr (they think they're Audi/VW at those prices?). R3500 recon done, collected and took the new 'tested' aircon compressor back to Bosch for fitment. Bosch did a full aircon flush (removal of debris in system from failed A/C compressor), A/C service/regas done with print-out - A/C not working! Bosch were kind enough to do a free diagnostic test and the fault found on their diagnostic machine was '01232 - Compressor Regulator Valve system, A/ Short-circuit to ground' which is a valve internally in the A/C compressor. The Bosch tech then explained to me that as per the diagnostics done and checking of the A/C plug/wiring (FOR FREE), the actual reconditioned A/C compressor is faulty (vehicle has gas and no leaks detected + no other A/C fault codes...)Returned with the vehicle back to Auto Aircon and was asked if I am sure Bosch knows what they are doing?! I was then told that Auto Aircon tests the A/C compressor on a bench tester and it's not possible that the A/C compressor is the fault. Furthermore, they want R950 for 1 hour labour and R550 for another regas to strip the compressor out of the vehicle and test it. Regardless if their compressor has a fault with the regulator valve or not, I must pay another R1500 to them for stripping and testing. Bosch (being an RMI approved service centre) was not good enough to properly fit the A/C compressor or diagnose the fault...(I could've let Pete down the road fit it and saved some money had I known) Auto Aircon are a money-grabbing business, not even looking to help or compromise on their labour rate with me as a client. Yes, I was still willing to pay for labour 'IF' the A/C compressor was 100% fine, I wanted them to diagnose the fault but extremely rude unprofessional personal didn't even want to discuss options with me as the client - workshop foreman didn't bother to come out and speak to me personally, sent out a rude lackie rather. STAY AWAY, it's not worth your peace of mind having to endure such atrocious customer service! (So now I have to pay someone again to remove the A/C compressor and take it, loose, to Auto Aircon for testing and for them to uphold their warranty). NB. Lindsay Saker VW Kempton Park will do it for R895 incl Vat and they will hold my aircon gas in their machine for free, once refitted they can regas and vacuum test A/C system For FREE - Now that's proper customer service! Take note Auto Aircon ffs...
