Vodacom customer service

One star to many, they have NO CUSTOMER SERVICE. I upgraded the week between 25 and 1 Jan. the agent told me there stock will be arriving 1 Jan thus I will be receiving my phone first week in Jan. I received no communication from them after the committed delivery framework but had to phone them to find out where my phone is just to be told they have no stock. Unacceptable Vodacom. They must believe and promote killing customer service and
