Customer dissatisfaction

I've been with vox for nearly 7 months and I've had countless connectivity issues. 1. They dont let you know when there are connectivity issues so you need to call them just for them to tell you there is issues, however instead of sending out all your customers a courtesy text to advise of Connectivity issues. 2. They increased my monthly installement without any communication to advise they would and why. I have a 20mb line uncapped for R819.00 however my new installement is R899.00. 3. I pay for 20mb download and 20mb upload speed but I get just over 10mb speed which is not what I'm paying for and I feel as this company is robbing me. I for some reason can't upload my screen shots of my speed test where you can see the date and time to validate my fibre speed.
