Fuel to be tested

I filled up at one of the engen service stations on the 3rd.January.Later that evening I was on my way to Durban CBD. On the N3 my car lost speed and switched off.It was late in the evening and had it towed.I contacted the SSthe next day and did not get any joy.I then contacted Engen HO and since then Im getting empty promises.<br> Im without a vehicle for the past almost 4 weeks and I run business and have to walk. Wheres the SERVICE???
