Today 07/25/2019 I went to return a merchandise at Walmart Supercenter on 3200 NW 79th St. Miami FL 33147. I got in line at 11:29 A.M. with 9 customers before me. There was only one employee assisting customers, there also were TWO supervisor just walking around the department. By 11:55 the line increase to 11 customers, by 12:05 P.M. two customers in front of me left because they can be waiting any longer, this will help me to get out the returned department by 12:21:33. The manager DYLAND PARADIS never offer an excuse or help to speed up the line. I'm a customer for more than 17 years and it is really a shame that this happened in a nice company like WALMART. That is why other companies GROWING. I love WALMART and I really like that this problem will be solve A.S.A.P. .-
