Telkom dont have a clear account policy

I have a few contracts with Telkom, and after the latest fiasco when they charged a full month's subscription for a new cellphone, for only three days. I asked the saleslady if I should rather come back on the 1st of the month, and she assured me that getting the phone that day (27th) would not result in any additional charges. . I queried this twice with her and she said there would definitely be "no nasty surprises" in the bill. I should have known better. I was charged for an entire month, when in fact I had the phone only 3 days. Their chat line staff say this is Telkom policy and there's nothing they can do about it. They gave me the email address of "the manager" ... but 8 days later I am still waiting for a response. Terrible service. And Sales staff who do not know Telkom policy OR were after the commission they would no doubt receive. I am now in the process of cancelling all Telkom contracts. I was even contacted this week by a Telkom Agent who was trying to sell me Fibre. Needless to say, my response to him was not good.
