Vodacom purposely blocks second sim access.....False advertising!!!!

I recently purchased a Huawei P8 light 2017. The reason for this choice was because of the dual sim property. Now that I have it the second sim does not work, I have been told that Vodacom purposely block this 2nd sim access. This is unacceptable as this is false advertising. I have been a Vodacom customer for more than 10 year and if this issue is not resolves I will definitely be leaving this network.
