Vodacom sells Dual-SIM phones but block the 2nd SIM slot

Dealt with Oz from Vodacom Shop in the Pavilion - a very ********* sales person!

Less than 24hrs ago my girlfriend signed a contract to get the new Huawei P20 lite. This is a Dual-SIM phone, and we even discussed the Dual-SIM with Oz the sales agent. He FAILED to inform us that Vodacom has in fact locked the 2nd SIM slot so it is unusable!

I contacted him this morning, and straight off the bat he tells me "We don't advertise that it's a Dual-SIM phone" and that it cannot be rectified and the contract cannot be cancelled.

Fine, looking through your deals you don't advertise that this Dual-SIM phone, with 2 SIM slots, is in fact a Single-SIM phone - BUT you don't advertise or inform the client that it is a Single-SIM phone either!

This is such a let down, we want the 2nd SIM unlocked or the contract cancelled!
