Unhappy client

I have been a client of Telkom for 4 whole years, never have I experienced such detestable service in my entire life! I make use of their uncapped LTE data services, In Jan 2025 I received my statement and there was an amount of R500 added to my bill, I went into their Alberton store to query this and was advised that airtime donations have been done from my WIFI? I was given a print out and the consultant dialed the 1 x cell number displayed and asked if I know the person on the other line, I said no. I was then told if I had shared my password with anyone someone could be using my WIFI? I was just shown away and there is nothing they could do to assist, I had a funny instinct about this branch though that they are not providing me with clear solutions / direction. I then decided to visit the Carnival Mall branch, no real assistance as well but the difference at least my query will be logged and I will receive feedback, I was told this takes 7 - 20 days for resolution. I then also proceeded to open a ***** case at the SAPS, needless to say the end of Jan my case was just closed and the feedback, my sim was used and it proves I did the airtime transfers?? I refused to accept this and requested same be re-opened as I need a thorough investigation done and solid feedback given to me - It is March 25 and nothing!!!! The fact that I need to be paying R1 500 thus far for a service I have not made use of is appalling to say the least and Telkom is literally showing zero interest in having this matter resolved amicably.
