Impossible to reactivate account

Good day,<br> <br> I have phoned call centre 7 times to activate my sim as it is hard locked due to account that was in arrears.<br> <br> Everytime they put me trough to someone else in a different department and no one is able to assist me or wants to assist me,<br> <br> Have been placed on hold been waiting. every call is 30min long,<br> <br> This is unacceptable and no one can give me answers,<br> <br> When i log on to my account it says payment due 29 February 2016 R638.99 but somehow i still need to pay R610 after i have payed R1143 that was outstanding.<br> <br> I cannot receive calls or make call.<br> <br> My Clients needs to get a hold of me and its impossible due to the fact that the line is hard locked.
