vodacom ********ly billing my account

The level of incompetence is amazing at vodacom, poor idiots...so I'm fed up, not only did i waste my airtime on garbage at vodacom but they keep billing me for a fibre line they no longer manage because i have already migrated to afrihost and they took over line rental and we have the order number vodacom approved and also released the line as well and now when i wanted to cancel my month to month with vodacom they told me they have no proof of a migration that took place as well as no afrihost technician that contacted them when they released the line as well...but i have all the info and proof with me so vodacom and the fools that work for them need to sort out this issue because you they wont be getting another cent from me and i also expect my refund of the money you ********ly deducted as well also i expect someone to get into contact with me that knows whaat they are doing because it is clear the rest dont have a clue whats going on...
