Scum of the earth

Had the most worst experience at this franchise taking my car in for a service. We have been using them from 2019. The car needed a minor service. So we usually pay with an eft and I asked the service consultant if this was ok and he said yes as long as I send through a pop back. At 3pm they call to say they will not be releasing my car bcos the money is not in their account and this is a company policy. They then ask me to come in and pay again with my card and assure me that they are reputable and will refund me etc. it was never pointed out that if an instant payment was not done that I would not get my car back at all. My husband has previously paid them via an eft for more than R10k and we had no issues last year. They now have changed their policy and do not make us aware of same. They also refuse to contact the bank to verify the payment.
