No Response from Vodacom

Since September 2014, the number *** was linked to my Vodacom account. I spoke to Clement (29/04/2015 - ref no: S3-83L9G-GKAN) regarding this matter when my debit order went off for the amount of R7342.58. I gave instruction that the number must be cancelled with immediate effect on the 29/04/2015. I have since phoned Vodacom on the following dates and spoke to the following people with NO results: 02/05/2015 - Eric Ngambaza, 13/05/2015 - Ms Petersen and 19/05/05/2015 - Progress Mazebo. I received a call from Zoe Bunyula ***
