Appalling Service

I've been served by retards at Vodacom. In January I opened a new contract which included data and ported my number to it, instead i was issued a new number, no data and billed. I raised the issue with call center, i was told the porting will be activated a month later, they corrected the mishap, billed me (again) and still no data. I opted to cancel the contract, gave them a collection address which is different to delivery address but guess what they sent the courier to delivery address. Called again to correct the collection address and nothing happened. Called to check status and they still gave me the incorrect collection address. I want my money back and the flipping error corrected.
