Closed an active line

I have been with cellc since 2005 and I am migrating from it once my contract expires. So much hassle and dramatisation for everything. I have 2 contract lines with them and have recently fallen behind payment with the one line as I am a student now. I have struggled to pay for both lines and I was told that if I wanted to close it I would have to fully pay the contract up. I asked if I can halt it up until I could pay it and they said no. Today I was attending and missed 3 calls from them. Now my up to date line has been closed. Let me say that the lines are not linked. They both have to be accessed separately even when I contact cellc. Some unthoughful person closed my line without notifying me, as I normally receive sms from cellc if my line is to be closed and I am given 3 days. Now I spoke to one male consultant and he informed me that my line is closed because the other line is in arrears. Let me remind you that these are paid even by different references. I am very ****ed off and hope that the person who put up the billboard in Sandton can put them up all over SA to show how cellc does not value their loyal customers. I would understand if I was owing on both lines. Im OUT!
