ADSL Intermittent and slow service, repetedly

ADSL Intermittent and slow service. This is what I have to deal with at regular time periods. I then phone , my router get reset and the issues just keep on continuing. Log a call and the technicians comes out to sort the issue out. Lines get tested. At first I was to far from the exchange, then cables were replaced, inside and outside of my residence. At times my services, especially during the week was and is exceptionally good and this includes some weekends too, but then, and most of the time on Saturdays, more frequently on Sunday's my services get so bad that I cannot even watch adverts on YouTube, which usually is not a battle with streaming media. I have lately subscribed to Netflix, and I am so frustrated in that I cannot enjoy something I'm paying for on a 10MB line. The 10MB line which is capable of such streaming services. If I get to talk to the Telkom's people, they will start suggesting different service, like fiber... is this Telkom's attempt to frustrate customers, forcing them onto a new course, whereby the customer have to pay more? I am so frustrated, and although this has been reported a few times (umpteenth times) and every time, sort of sorted out by the technicians, I still have to phone Telkom various times to come back and fix whatever needs fixing, again!. Telkom do state that they will refund where any services lacked, but who will refund my Netflix? Not Telkom! Telkom will you ever be fixing my services, so that I can enjoy for what I'm paying for! My account is never in arrears, but your services, is! Telkom you are bleeding customers, but what do you do to keep them?
