Non Existent Customer Service -

I renewed my contract on Black Friday with Nokabonga(Vodacom online) who called several times when she wanted the business. Today the courier phones to tell me they need to deliver my order, however my order needs to be in ***** address. Nokabonga took the liberty into her own hands to change my address on the system. I have tried calling Vodacom more than 6 times being put through various departments, speaking to various people,after holding on for more than 30 minutes each time,but no one is able to resolve this , I was even given an email address that cannot receive emails to send documents through to. Customer service cannot ever answer simple questions pertainging to customer service. Vodacom! Why cant your customer service be as quick as your new sales when you want the business! Please train your rude arrogant staff Please could you resolve this ASAP!
