Frustrating & Angrily annoyed

Vodacom called me offered migration with no increased installment, only to find out that there is an increase from R699 to R1080. Now my services have been cut and there is no help. I must wait for 7 days without a phone that I use for business while they investigate. They don’t even send statements, I find out when my line is cut. I have been paying my normal premium of R699
