Poor vodacom service.

I have been trying for 10 days to get a matter resolved with my email account. I have called Vodacom about 10 times, only to be told a technician will contact me within 24 to 48 hours or within 3 days and I just have to wait. Till this moment no one at Vodacom customer care has taken this seriously, there was at one stage not even notes added to my query. How is it possible that no technician is able to call me in 10 days. Empty promises of call backs just not happening. This matter is beyond ridiculous by this point and my business is suffering due to this issue. Please can this be resolved!
