Terrible service. Lies and delays

Vodacom advertise to upgrade your phone on line. It's taken me over 2 weeks to upgrade. The person I spoke to last week assured me that the phone would be there within 3 days. It took 5. They confirmed a sim card would be delivered with the phone. I open the box. No sim. I call the call centre. A sim will take 2 weeks and no they cannot call a local Vodacom shop. Ridiculous. My data I bought on the sim will expire. Really this is the equivalent of theft. Vodacom sit with all the cards in their hand and we tge customer must just pay. I must now go to vodashop and pay for a sim or wait 2 weeks. I am so frustrated. My sons contract is up for renewal and I'm quite happy to change to mtn.
