Spanner light on and ford blaming the fuel station I'm using

I bought my Ford ecosport in 2019 and this year took it for 30000km service and **** started happening. 1st it was the brakes, BB Ford Menlyn said that they cannot fix the brakes since they are still okay. But I could hear that funny sound ? and insteaded that they replace them. After taking my car within a week the spanner light came on and it started losing the power. I called Menlyn again to tell them, they said I must bring the car in. Took the car in and they fixed the engine injectors. Went to collect the the car again and still the spanner light was on and they are claiming that the technician did not see the light and test drive the car to see if it okay. Took in again and still with no courtesy car from Ford, they changed the battery and they could detect the problem. After that they started asking me which petrol ⛽ station I'm using cause mayve the fuel might have water ? in it. Paid R2500 for them to take the fuel for "tests", tasts came back "FAIL" because of fuel mixed with water. Had to pay R5900 for them to drain that and put in new fuel injectors. Went to take the car and its still doing the same thing. I'm so disappointed with ford cause they know its factory fault and they have to give me a new car but they are coming up with lame stupid excuses that the fuel damaged the car. Guys pls don't buy ford it's a ****.
