vodacom online sales no delivery

Called vodacom online sales on Sunday 01/02/2015 to order an upgrade for my phone line. The phone was not delivered and somebody at Vodacom even went and cancelled the upgrade order. Every time we tried to find out what happened, nobody could help us. Every time we requested to talk to a manager we were told no. Do not order for Vodacom online because you will not receive it and nobody will be willing to assist in any way. Never heard of a company that will not allow you to talk to a supervisor before. We have 7 lines with Vodacom and that does not even help. Guess we will not renew this contract via upgrade and start changing all the contracts.
