Poor quality of storage of fuel i believe contaminating it

Complete disbelief that i was not taken seriously regarding a very serious matter. I believe and can physically see that there is something odd regarding the fuel (diesel) i purchased on Saturday the 28th July. On monday my car developed a weird jerking motion and since yesterday has began smoking and misfiring ridiculously non stop and did some investigating and in the diesel was an odd smell but it was higjly flammable and would ignite to an open flame very veryeasily. I phoned thr station and they were highly unhelpful. I am furious as they wouldn't even comr see the sample i kept aside. I hadnt put any more diesel in what so ever. My injectors weren't old and my motor was functioning 100% and is now not.
