i cannot even understand a single word you just said.

I think he/she trying to say,

1. He/She try to buy an item from www.themarathonshop.com.my for RM 0.00
2. He/She got the conformation email on the item he/she try to buy
3. Then the owner of www.themarathonshop.com.my sent an email saying that the item is mistakenly priced at RM 0.00
4. The owner of www.themarathonshop.com.my is sorry and try to make up by giving he/she 20 percent discount
5. Now he/she is so pissed because he/she cannot "buy" the item for RM 0.00

Correct me if im wrong.
