Line being locked because Vodacom didnt debit me

Im so tired of this contract i cant wait to cancel it soon.<br> I called in for my debit order date to be changed stupid consultant doesn't check the dates when im able to do it she does it anyway vodacom doesn't debit me which i dont even notice as 8 years have gone by and always did i get debitted by them. Then to top it all of she cancels my reoccurring data bundle i don't know why!!!<br> Now vodacom has this automated calling system calling me to make payment when it wasn't my fault and threatening to block me. I called in twice and the consultants keep promising somebody will get back to me but nobody has. Could somebody get back to me and while they at it get a quote to cancel this contract i have had enough!!!<br>
