Disappointing service from Vodacom

I have no internet connection on my router from Saturday. I called the call centre and the agent tried her best to assist me, however, she was not able to restore my internet connectivity. She logged call with a technician and she said it will take 48 hours to receive a response. It is now 3 days (72 hours) without internet connection and we have not received any call from a technician. I have called the call centre to follow up multiple times however there has been no help. I am extremely upset and disappointed with this service. I work from home and have to study and that is very difficult without wifi connection. Over the past 3 days have incurred so much data costs and I will still be expected to pay for the wifi in full at the end of the month yet it is going onto 4 days without internet connection. I want Vodacom to compensate me for the additional data charges I have incurred because this level of service is not expected from a reputable service provider like vodacom. If this issue is not properly and timelously resolved I will take by business elsewhere!
