I have been AT&T Diamond Bar Store customer for 9 years. In December of 2019, I upgrade my service to $30 per line. However AT&T charged me $40 per line in two bill cycles. On 2/27/2020, I visited AT&T Diamond Bar store to question about the extra Charges. When I was waiting in the store , I noticed the front desk staff was explaining to the other customers in English with patient , polite and respectful manner . When he helped me with my matters, and he explained the reason of my bill overcharged , I was not Signing up for paperless statement, so that AT$T charge me over $10 for each line. He spoke To me in Mandarin. But he was in inpatient, rude, and reproached manners to communicate with me. I asked what was his name, he could not provide to me. When I requested to speak with his manager, he said he was the store manager. I felt the manager discriminated Chinese speakers even though he was native Chinese speaker.Response from AT&TMarch 2, 2020Hello Qingxiu.

The data plan on my phone was blocked. The techician in charge at the store spend a good amount of time helping me to unblock the phone. I tried another store previously, but the employee was not so helpful. Also, I asked him about a buffering issue that frequently occurred when I watch live streaming on DirecTV Now. He said he will bring this issue up with the DirecTV Now rep next when he see them - August 20, 2018
