Terrible services from Vodacom retentions team.

I called to cancel a cellphone contract and thereafter offered a retention deal. I explained that I am not able to access my sms and would not be able to accept the deal by sms as a result. I have been promised to be called back by the confirmation team since last week and nothing materialized to date. At a moment i cannot even contact Vodacom since I have reached the maximum number of times to contact them, this is as per IVR on the number ********** . The IVR referred me to a non-toll free number ********** 004. I dialled the number ********** 004 and i held for a long time until i hung up since there was no response. I can be reached on ********** 585.
