Intermittent connection

Hi i have been experiencing intermittent internet connection for quite a while , were i have reset the router couple of time per day. 3 days ago my phone line stopped working and the ADSL line speed synched on 3072kbps instead of 4092kbps as i have a 4Mbps line. I raised a fault with Telkom they fixed the line but the ADSL is still intermittent and only synching at 3072 so i raised another fault 795CRK180116 which was closed the next day in the morning without anybody attending and i just got service restored. The service is not restored and is still have issues. I have logged another fault again wiht reference 1191CRK190116. Please fix urgently as we do expect telkom to provide a good service if they are charging 770ZAR/months.
