Lack of customer service

I am a contract holder and even though I have made my payment my account is suspended for a week already. The stores have unlocked it and dont understand why it is not unlocked on my side. When trying to phone customer care you NEVER get an answer, they say due to striking but this has been the **** service you get even before. They striking but their staff was able enough to suspend a paid line yet they the staff are not available to sort out the issue. So I am paying for a line that I have not been able to use for a week already and the days are just adding on. I am sick of it! There is always issues with getting hold of the customer care line. In stores customers are venting their frustrations to which you get a response of \There is nothing we can do
