Bad and inconsistent line speeds

I upgraded to a 50Mbps line on 20 March. A few days later, Afrihost’s CEO announced that customers would be upgraded to the next level package at no extra cost from 1 April until the end of May because of COVID-19. On 1 April when I queried my line speed, I initially advised this would be done by 3 April. On 3 April I was then told that it would be upgraded on 7 April. Today, it is 14 April and it has still not been done. What has been worst is that I am paying for a 50Mbps line but my line speeds are consistently lower than 20Mbps. When I checked my speedtest now, I am on less than 27Mbps upload speed. This is making it difficult for me to get my work done and is extremely frustrating getting a far lower speed than my actual package of 50Mbps. My package on client zone shows as 50Mbps when it should show as 100Mbps based on their CEO’s message. Don’t make promises you cannot keep and at the very least, you should give customers the service they have paid for. Please investigate and advise.
