Poor service

This is a very bad company today I got a call from vox I ask the guy why is my bill R895.10 for this month when I payed R807 he told me that is the amount to pay but I ask why he told me on the 1st of May 2025 the prices increased but I didn't get a msg or notification about the price going to increased then I ask him I had a 75meg line why does it show I have a 100meg line he told me that I never had a 75meg line I had a 35meg line I told him when I started with vox 2yrs ago I had a 35meg line then that package weren't available anymore then they migrated me to 75/75 for R807 he told me that on there records it don't show I had a 75meg line so did I Pay R807 for a 35meg line while my service shows I have a 75meg line and now it show I have a 100meg line so for what package do i really pay for it seems like you guys are busy with ****ming me for paying for a 75meg when its a 35meg now you bill me R895.12 for what a 35meg line or 75meg or 100meg you are loosing clients for poor service there are alot of customers complaining about your bad service and I'm not happy at all for what you guys are doing I need a explanation on this post
