Vox - poorly trained staff

VOX Bloemfontein is the the worst.

I have been getting emails from VOX saying I must update my password, with a link to click on the email. I was suspicious so went into the VOX branch. NOONE could tell me if it was spam or true. I was told to email a copy of the email to their office. I did so and got email reply saying yes I had to update my password. This morning I again got an email saying I had to update my password or face suspension of my service. I went onto customer portal and could not manage this, so once again I went into the VOX branch in Bloemfontein. This time I was told no I must not update my password. DO they know what they are doing. If my account gets suspended because of this (as they are threating in the email) I am going to explode!!!!!!!! I have been twice into the branch and matter not solved!!!!!!!!!
