Shipments have delays, the information is not the same in MercadoLibre as in the company that makes the shipment, eg: ANDREANI. For 10 days the return shipment has not arrived, time, money and the possibility of selling the product are lost. I have already made the complaint in COPREC (protected consumption). There is no way to contact MercadoLibre. Don't be afraid to answer a phone that nobody eats. If you want to digitize everything to save time and money, be more efficient if you don't have an alternative to talk to a suitable person and solve a problem. Break that Oedipus complex at once. After wasting time, solved through twitter. Now they have to update MercadoLibre's reputation system.
