Shocking Service Levels

I have 26 Vodacom contracts made up of both of data and talk time contracts. I have a number of contracts that were due for renewal and this was first communicated to Vodacom Corporate on 21st May 2015 via e-mail where I requested a subscriber report to see which contacts were affected. After numerous e-mails and phone calls I am no closer to renewing any of the due contracts. Very few of my e-mails are answered and my calls are not returned. My last correspondence with Vodacom was to inform them of my dissatisfaction and that I intend moving to an alternative service provider. STILL NO RESPONSE!! This type of negligence is unacceptable!!! To add insult to injury, this is the third time that I have been through this frustration with the same person at Vodacom when trying to renew contracts. I am moving to another provider.
