Poor telkom adsl and service

Good day I have a complaint to raise about Telkom. I have been a telkom customer for more then 5 years now. I have 5 contracts with them and yet I am being treated like s#$t. I have a 10mbps adsl line at my house and for the past 9 months -since August 2017 I have complaint about bad network. Now its not resolved and i am being contacted by telkom on a daily basis and they ask me is my service restored. If I tell them no they just say thank you and hang up again i have a 10mbps adsl uncapped line and i receive less then 4mbps and have no wifi from my modem anymore. And direct link to any device is less then 2mbps. Telkom doesnt care about their cuatomers only about our payments on our accounts i pay for a service that Im not receiving and when complaoning they just do nothing about it

Thank you Jaco fouche
