No customer service at all from MOTO-LUBE Fourways Crossing

We have a Ford Fiesta 1.0lt Ecoboost 2015 model that's motor siezed on 100 200 km mileage on the 6th July , 2020 with no warning what so ever . No warning lights at all . (We have a case against Ford as well that is pending ) - On 31st Jan 2020 we entrusted Moto-Lube Fourways Crossing with the service of this vehicle due to it being out of service plan with Ford . What came with this was a "6 months or 10000km guarantee" - Jaco at Mot-Lube offered telephonically to assist , to go and take a look and see if there is any way forward as Ford want R92000 in total to repair the vehicle. Never once did he ever get back to us , in fact Jaco has avoided all email correspondence - NEVER BOTHERED RESPONDING TO HIS CUSTOMER !!!!!! POOR SERVICE . What is sad is my family has serviced about 4 vehicles with them and I have forwarded numerous customers to them . What is concerning is it could possibly be something Moto -Lube Fourways Crossing did that caused this major incident with the vehicle ? Why do they drop their customers when the chips are down ? Surely at this stage you stand by and advise your customer ? All I can say is be wary if something goes wrong with your vehicle and you use this company , you will be left in the lurch with nowhere to go .
