Poor service from ford

Ive took my vehicle to Ford Secunda on Wednesday 14-09-22 and got it back the next day. They only did a diagnostic test, for 2 days +/-R870 later that I had to pay Before I took it there. I was at 2 other companies that gave me the same results.(Fuel rail high pressure sensor low) But now ford is telling me a different story(3 injectors faulty and fuel pressure pump).On the collection day they told me that they will email me the quotations and the report that I need to send to Outsurance for my motor warranty. On Friday when I phoned for the documents(12 o clock) I was told they are not allowed to give it to me. It feels like something fischy is going on. I don't believe that's true. Even if I want to pay cash they don't want to give it to me. So I've got no proof on the parts that they say are faulty or prices. I've even phoned other ford dealers for prices on the fuel rail and Secunda was way more expensive than the other dealers. I phoned customer care emailed them and still no feedback. Really poor service
