Worst product

I bought Spar cake wheat flour 2 days ago. Today was my second day using it. I must say its the worst pile of sh*** I have ever come, across. It doesn't get cooked at all, no matter how long you wait for it to be cooked. I regret wasting my money on this product. Unfortunately I threw away my till slip and can not send it back. Do you people even check your products or you just send them out for selling???? Now I know to stick to Snowflake and Sasko
