No feedback on new contract

I have been trying to add a contract to my existing contract for almost two weeks now. I emailed like minds on Thursday last week with all my documentation and have received not a single word from them. They cannot be reached as their department is not linked to the call center so the only way to get in contact with them is email and after 3 follow up emails, absolutely nothing in return. Not surprising Vodacom, your rating speaks volumes for the inefficiency and inadequacy of your servicing departments.
