I went to Costco in Burbank on 1/21/20 and wanted to change my wireless service from Verizon to AT&T but the person in charge made me to wait for one hour and still not able to switch my phone. I am very disappointed this sales man asked me 5-6 times for my social security and asked and kept my ATM debit card for over 15 minutes not sure if these guys are legit.
then after I called one of the managers I found that this Kiosk (Wireless Advocates) does not belong to Costco. If I knew this in advance I was never going to deal with this kind of vendors. My cell phone was not working for 24 hours and I had to pay AT&T even though I never swtiched to AT&T.
Since I had this complaint, I am receiving a spam calls 3 to 4 times a day.
