Misleading sales pitch

I can't believe that i am buying data bundles everyday while i hava contract with Vodacom. I was so happy with them that i renewed our contract. This time around someone decided to add their HOME INTERNET option on my package. I had no issues for about 3 months then started experiencing slow connection. For more than 6 months I've been calling Vodacom to report the issue and they all refreshed my network which only worked for a day until my last call in December when a consultant informed me that the package i am on only works on a router. Vodacom please restore the package that i was using and remove your home package that you added without my knowledge
