I sent a buyer in basic package very good quality.
.
Then the buyer asked me for high quality in basic package, but it is not possible in basic package!
Then, I offered to give him high quality in basic package for great satisfaction but he ignored me and asked me for refund and repeatedly threatens to give me the 1st review!
I have worked very hard for this project. It is very sad and disappointing for me!
I can't understand that, what should i do.
Please, help me and solve this problem.
