Webafrica - Very Slow response - No response from Senior Management on my queries

I am currently paying for 1Gig download speed and 2 Meg Upload speed. For more than a month now I am only being able to, at best, download at a max of 10Meg speed. I have had multiple interactions with their bods and their staff and they are keeping resetting the ports on their side but nothing changes. It works for a little bit and then goes back to around 8 to 10 Meg. They day before yesterday my Fibre was totally down and it took them all day to get it back again, The call was closed but the speed is still sitting at around 8Meg download. My Wife and I are working from home and this impacts our income stream. I have also asked for this to be escalated by the helpdesk to their senior management but it is obvious that nothing has been done about it. We have done every possible test etc as per the helpdesk and nothing is working. Message to Webafrica's Senior Management. I need this to be resolved by tomorrow.
