why do you want to give him 1 month?

Where got such thing as supplier ask for FULL payment only can take order. I pay you, you give me stock lah. If got no stock then I wait lah. That's all. What kind of supplier is this? No money to do business until need to take buyers money?

Seller cannot run away from his responsibility. TS deal with seller not with supplier. Want to make money but don't want to take responsibility? Where got so easy? Like that any tom, d*** and harry can sell products lah. Then got problem said not my fault and push it all to supplier.

This is either a conjob or a very useless seller.

If seller is conman then he will give all kind of excuses not to return your money.

If seller is useless seller AND responsible for his sales then he must return the money immediately.

If seller is useless seller AND irresponsible then he must be blacklisted.

1 month is too long to wait. All the conmen's tactic is to delay and cheat more people.
