The seller has to give you a change, because obviously, it's a quality issue, and it's a well-known brand, and they should have a shelf life. If he doesn't give you a change, you can sue the consumer association.

According to the regulations of the three guarantees of footwear, it is possible to return, replace and repair the glue within 1 week. With the shopping voucher, go to the operator theory. Remember, consumers are asking for rights, not compensation.

According to the three packs should be replaced, but the other party proposes to replace the soles, it is recommended that you receive. Because it's not worth the longer cycle, more effort and resources to replace all or parts. Although consumers want rights, those that cover the public interest can still litigate, and other lawsuits have no value.

Generally, it is a monthly replacement (not for human reasons).

Just call 315 and forget it.

This friend, I have also encountered the problem you encountered, what customer is God is false, it is useless to find anyone, time-consuming and laborious, the most direct way is to find the boss or management of the leather shoe counter in this shopping mall (store manager or the like, the general boss is not there), don't tell him any reason, directly scold him (don't do it, otherwise if you don't do it, it's not easy for him to do, even if you can beat him, he will call the police, and then the police will come and it's not easy to do), If the police come to persuade you, you will even be scolded by the police, but you must remember one thing; You just can't do it. If you scold the boss or the manager and ignore you, you will scold him a few more times, and then ask him if he will change it, and if he has time, he will stand at the door of this specialty store, and persuade him not to buy shoes when he sees a customer coming to buy shoes, so that the owner of this store will find you to deal with this problem.

Trust me, that's right!
