data not received

I went to Vodacom Tubatse Crossing to do my upgrade from a top up to 1gig data bundle. On the 1st of April I did not receive my data. I called Vodacom call Centre for help they responded with an sms on the 2nd to inform me that CIC department is investigating my query. On the 6th I phone Vodacom again due to no respond since the 2nd, they told me CIC only works during working days and they will credit me with my data the following day (7th). I have waited Tuesday and Wednesday still no respond. I called Vodacom again today the 9th I was told that my query is still pending. I don't know for how long should I wait for the service that I'm paying for. To what I know if you miss one payment with them your account is suspended immediately, but for poor customers like me you have to wait and beg for the service that you are paying for. This is too much I want to receive my data as per contract that I've signed with Vodacom on 18th of March 2015, ASAP.<br>
