Deleted my number & refuse to assist

My data line was with Vodacom on ***. Yesterday they deleted my number of the system.<br> I then telephoned the call centre & requested that my number be restored. The refuse to help me restore it. They then informed me that it will be recycled. All my data & emails will be destroyed. I use this line for work. I find it totally unacceptable that they refuse to help me restore my number.<br>
