Not a recommended service

I've been with Vaal Networking for years now but as of the last year their quality, speed and service has downgraded immensely. I am paying for a 4mbps uncapped line but I rarely get speed more than 1mbps. When I contact them, they fix it and it only lasts for the day but then the next day the same slow speed. They know I have been experiencing problems with my connection because I constantly call and WhatsApp on their after hours line, taking screenshots of my slow speed but there's never a permanent solution. I am so frustrated and will not be recommending this service to anyone. This company is not the same anymore. They dont care about their customers anymore and are ripping them off by providing slower speed as paid for.
