Vodacom customer service

After numerous calls to Vodacom regarding my data n airtime that I lost I was told they would investigate and I will receive a response within 24hrs. No response received after 24hrs, I called again and was told it will actually take 7 working days to complete the investigation. Two weeks later, which was yesterday, I received the below SMS. To me this is saying " I've concluded the investigation, you're talking nonsense we never took your data n airtime but here are some freebies, coz we know that's what you wanted. now shut up" Who ever sent the SMS couldn't even be bothered to call me after so many calls to your call center!? This is a personalized SMS, it's not an automated SMS so someone wrote it and I want that someone to CALL me.

SMS: Good day. Please be advised that after investigation I can confirm that the billing is correct as per the volumes of data that were processed. I recommend that you consider installing a data monitoring tool e.g. ?My Data Manager? (available via the internet/Appstore/iTunes) to assist with tracking usage. Events on your device are not controlled by Vodacom. Please be advised that I have loaded 500Mb and R100 as a once off gesture on your account.
