Has not responded to my emails

On the 7th December I sent an email to customer care requesting invoices to be sent and they responded the same day informing me that the account is managed by Vodacom business. They gave me their email address and to date I have not heard from them.<br> <br> Email sent to them on the 07th, 08th and 09th requesting feedback.<br> <br> Well I suppose its no surprise after reading all the complaints about Vodacom.<br> <br> Hopefully after sending this I will get some feedback
