Vodacoms poor reponse to complaints

I lodged a complaint against Vodacom on this website on 28 October 2015.In light of my previous similar complaints which have also remained unresolved I have been more than reasonable in allowing Vodacom a last opportunity to address our problem.Vodacom has done very little if anything to help us.Their service is shocking.If we have a signal it takes me best part of 15 minutes to send a 100kb email.Phone reception is virtually non-existent.My company has religiously paid all its subscription fees.Legally I now give Vodacom seven days to resolve our problem failing which I reserve the right to cancel all my company's contracts with Vodacom.Once this happens I intend to give Vodacom all conceivable bad publicity their poor service and arrogance deserves.
