Uhm no don't do that.
I had a 50 Mbps line with them and 90% of the time the line speed was under 10 Mbps. Decided to opt-in for the double-up promo and thought if I get 10 Mbps on a 50mbps line then Ill probably get above 10mbps on a 100mbps line and it wasn't the case. on the 100 Mbps line had speeds below 8mbps but sometimes when I restart the router it will jump up to 40mbps and slowly but surely make its way back to 8 Mbps.
Decided to move away from Afrihost to Coolideas.
I have a 100 Mbps line with them and I get the following results

During night time, I get more than 90 Mbps download and 70mbps upload
Asked Afritoast support to help, they said that it the router, and If they send out someone it's going to cost R 1000 if there isn't anything wrong with the line, with my luck everything will look super on the day the techie comes out and then I have to cough up 1k.
The funny thing is I am using the exact same hardware that Afrihost gave me, just with CoolIdeas details
So happy I don't have to deal with afritoast anymore
