Poor service

I placed an order last week for an upgrade online because I'm not able to do it at a store (turns out my account is still on a legacy system?) Order went out for delivery on monday, but failed because the agent didn't include my contact number. Contacted vodacom today to follow up on order, however after 4+ transfers there was still no-one to assist me with the issue of the delivery. Agent advised that a manager will contact me shortly - to date no one has contacted me back.
