I have a 2GB that grows to 5 GB pan. I've had it since 05/17/15. The cost is $35/Mon. It is $30/Mon if on the automatic payment. I am. The dataq is supposed to grow by .5 GB every six months if payments are made on time up to a maximum of 5 GB. My payments have always been on time. My plan did increase from 2048 MB to 2560 MB after six months. It was to have increased to 3072 MB in April, 2016. It did not. I had to purchase an add-on data package. I called the last time on 07/19/16 to inquire about when I would get the extra data. After profuse apologies, I was told that I would get 3072 MB effective 08/18/16 (my cycle beginning date). It hasn't happened. It is very difficult to get to talk to a live human being. Has anyone else had this problem?
Also, the "growing data plan was changed to a 512 MB increase every three months if payments are made on time, but that was after I signedup for the original plan.
In that case, then I would need you to please send me a private message including your number and PIN code to further help you.
I'll be looking forward to your reply!
