Worst service ever!!!

3 days of no wifi and 26 calls later with alot of promises and still no feedback I am still without wifi. Worst service provider that I have ever in my life dealt with! Earlier this week someome at vodacom made a mistake and cancelled my subscription which took them 26hrs to resolve, now again on Friday my wifi disconnected, 26 calls later, nobody has called me back on why my wifi is still not working!!!???
