BAD CUSTOMER SERVICE

Good afternoon, I would like to report a bad experience on the part of the employee GREG M at the 1520 Stoneridge mall rd store, I went to pick up a device that t mobile had sent me for exchange and I was very humiliated by him treating me with little respect and being super nervous without any kind of emotional control to work with the public even his work friends he distracts and everyone is afraid of him.  I made another purchase of a JBL and my friend made a plan with one of the other employees who was the one who apologized and tried to help us.  I'm writing this email because I don't think it's fair to have people like that in the job market, I'm from Brazil and I've been working with people for over 20 years and I can't stand injustice and discrimination. Something has to be done. a more harmonious climate in the work environment, thank you in advance.  he did not deliver my delivery I had to call the customer service asking another store to receive it there is no total disregard😭
