Horrible Service. Charged for a returned router

Please note that I will not be making any payment on this account.The router was delivered to me in Cape Town, but upon receiving it, I was informed that it was not compatible or simply did not work in my complex. As soon as I discovered this on the 23rd of April 2024 , I immediately contacted the sales representative who assisted me, Chulumanco Mgwangqa and told her about this and how disappointed I was that this was not told to me beforehand. Despite this communication, no action was taken by WebAfrica to collect the router, even though it was initially delivered to me. Subsequently, I was incorrectly debited R1,000 for this router—twice (September and October 2024). I reversed these debits and once again informed WebAfrica that I would not be paying for a device that I could not use and that they needed to arrange collection. Again, no action was taken although they (Nobuntu Mthembu to be specific) asked me for my address and I gave it to them and told her they can come collect anytime. Fast forward, I relocated to Johannesburg. On the 9th of January 2025 I made the effort to personally drop off the router at WebAfrica’s offices in Centurion. Given that the responsibility for collecting the router was WebAfrica’s and I went out of my way to return it at my own cost, I fail to see what I am being charged for.
