Good Communication is KEY for Great customer service

Really disappointed in the customer communication procedure at Bosch Menlyn. I think that it is only professional to ensure your that customer knows exactly what to expect upfront. For a high profile company like Bosch there must be a better form of communication than saying " I told you on the phone call you have to pay R862.00' I would like to hear that recording to get confirmation that I was told this. I think Bosch should make sure customers are informed in writing that Bosch will do a diagnostic as SOP and charge R862.00 for EVERY check-up even if the customer asks to ONLY to check a mechanical part. When i queried this, I was told that 'You were informed that a fee of R862 will be charged for the vehicle in the communication before you booked the vehicle for the inspection'. Please can you proof that and then I will be 100% fine. I was also told that 'We have a standard price list in our reception which list the price as well'. Please let me know if any one of your staff handed this to me or showed it to me. I was also told 'Then we had to write a report''. Please show me this report, I never received this 'written report'. After my suggestion on communication the response was 'I will however update my procedures to make sure that it is very clear that our standard price for a check and quote job is a minimum of R862'. Which means that Bosch agrees that their communication on charges is not clear and have gaps. So basically, I am saying I know that you have to charge for everything checked and I understand that , but please confirm your SOP diagnostics and cost and confirm that a customer agrees before commencing. All the other professional auto repair places do that. Thank you. Waiting for the confirmation that bosch mentioned the charge to me and the Written report that I paid for. Kind Regards
