Afrihost and Openserve Bad Service

Hi i have had afrihost account for 5 or 6 months i have a 20mbps account and line but i have never had faster connection than 5mbps and its always off 5 days in the week its off and then suddenly it works again for few days. Every time i report the issue and then they report it to openserve and nobody can fix it. I am paying R1000 for a bundle deal where i lose all the time im paying for something i don't get. I have now canceled my account the 11th of August 2020 and i have payed for the entire month but now it aff since the 11th. I want a refund of the days the internet isn't working for now and the month's before. Im basically forced to cancel the account because of utterly the worst service between Afrihost and Openserve they are very quickly to say they don't install any lines to the premises but they have a new Pure DSL Service with a new line installed cutting out Telkom. Also i would rather take Fibre but nobody can help with Fibre there's 2 few school's a block from me and LTE isn't a option.

Please help
