useless

<p>My upgrade was due in December 2015 and up till now I am unable to upgrade my contract due to system error which changed the date on their system . Despite numerous complaints and cases the problem as still not been resolved and now they decide to stop my data on the line which is ridiculous. They send me a message saying they are closing my case due to no contact ywt no one tried to contact me. Managers at the branches are of no help and customer care agents are absolutely useless and have no clue what they are talking about. </p>
