Where can I write a positive review for two T-mobile store employees

I went into the T-Mobile store on cope (3SAP) I had dropped and cracked the glass on my watch the first time I was in there the young man was so rude told me my watch wasn’t covered and threw a piece of paper at me and said call this number and walked away. I went back in today about 3 weeks after first incident and I was greeted by Zaybrea and she was so helpful and informed my watch was covered and walked me through all my option. She was very helpful and pleasant. I couldn’t find anywhere where I could put good feedback besides here, so I hope this makes it to her. Zaybrea is amazing and friendly and helpful and deserves to be recognized for her good work. Thank you!!
