I am trying to upgrade 3 of the phones on my account and am having major issues with my online account and app. I am trying to take advantage of the sale that ends today, 12/1/19, and have been trying since Friday morning (now Sunday). I went to the store Friday and the associate told me that I could purchase the phones online instead of waiting in line in store. They told me that I just needed to make sure and checkout separately for each individual phone line. I then made an attempt to do this Saturday morning. I purchased the first phone with no issue, but then when trying to purchase the second phone the system tried to get me to add a line and would not let me purchase any more phones for the other lines. I then contacted customer service and they said I had to add each phone individually to the cart and then check out. They cancelled my original purchase so I could make the new one. Once that was done, I opened my app and saw that I was logged out. I then attempted to log in and it told me that I could not log in and that I would need to wait till the next day. Called customer service again and they could not figure it out. Went into the local store and same issue. So I waited until today, was able to log in, and attempted the method that customer service told me to use. Once again, unable to add more than 1 phone and when going back in the system was locked out and the system says I cannot log in until tomorrow when the sale is over. Any help would be greatly appreciated. I have 5 phone lines with Cricket and approximately 10 across multiple family members and would like to have a good experience with this purchase.
