Contract mixup, inefficient and irritating

A contract application was initiated online and subsequently concluded via the phone. The agent asked whether or not I wished to use the same number, to which I agreed. Within the next day or so, the device was received with no SIM card. (I assumed that Vodacom assumed that any SIM fits ANY phone). I queried the issue with the chat agent, to which she suggested I purchase a SIM (which should have been free) and do a SIM swop at the branch - to which I obliged and went into a branch (which I wanted to avoid by doing it online). SIM purchased and SIM swop complete ... the agent at the branch informed me that no contract exists on the system. I had to call in again to query this (WTH?) To which the fourth agent that put my hold finally advised me to call again to activate the SIM swopped card on to the contract that was taken... Why should all this be so cumbersome and inefficent? I have taken out an MTN contract in the past with similar circumstances and there was ZERO hassle. Kindly resolve your policies, and please fix my situation without placing me under any inconvenience as I am paying for these services. This is not your favour to me...71
