Upgraded twice - Still no upgrade - Deal now not available anymore

If I could give a worse review, I surely would. Up to date, I have upgraded my data contract twice (rather, I have attempted to) online. Four weeks later and I still have not received anything. No answers can be provided and no feedback is given ever. Now, the data plan that I was suppose to upgrade to, is no longer available. As is, my upgrade has been due for more than a year. Worst Service Provider in the country by far.
