Still no response to ADSL line

After losing connection for nearly 3 weeks. My internet connection is still highly unstable. Whilst the Telkom website says my area can get 10mbs broadband, Axxcess has claimed that I am unable to get anything more than 1Mb. Tried contacting Telkom via phone (have to wait over 30mins for an answer), or through their chat (does not work anymore). Technicians claimed they would come but never did.
