AT&T Store Diamond Bar Diamond Bar

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.

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

Everything was fine in the store, was shown the correct phone and all. However was told I was told my phone would arrive to me within 2 - 3 business days. It took 7 days to arrive to me. I needed it asap.

The sales persons at this shop are really professional. They know how to help their customers.

Very good customer service. Sales representative was very courteous and polite.
