I have come to this mall in order to buy a mattress + mattress + bolster.
And the bazaar clerk first tells me that she could not find me these products because I had back pain and I could not make any effort. After a long conversation, I managed to convince this person to go and look for the products. After 20 minutes he returns informing that he could not bring them because he did not find them in the warehouse and that there was no one in the store to take out and organize the products. I am going to the customer service area commenting on what happened. And here, too, they do not give me an answer that convinces me. I do not understand. As workers in this center stop selling products, it is as if they do not care about losing customers.
