Incompetence of staff members at call centres

I have been struggling to get reconnected on my previous number *** which ultimately was given to another customer. I have been struggling with this matter for more than 6 months now ,i have spoken to Petronella mathebula who confirmed that my reinstatement will be done and my debit order reactivated .we concluded on an amount of R428 per month but to my surprise an amount of R700 was deducted from my account and the next month no deduction went off. i then phoned this Petronella individual who then again said she will reactivate with no further charges and send me a blank Sim card where i gave her an address to sent to,the Sim card was never sent to me . i then phoned again vodacom where i spoke to Tinyiko Baloyi who i again gave two addresses and to date i still have not received my Sim card or my account reactivation . I feel this is sheer incompetence from vodacom staff members and yet they are team leaders . My frustration is that i have to call constantly to get feedback from vodacom and this whole saga is having a huge negative impact on my ITC profile . Please i need help with resolving this matter asap !
