Pathetic Service Provider

Every 2 or 3 months im having faults on my adsl or landline. Every time my service is intermittent, loosing signal or my phone line makes a static noise and i cant communicate with the other person. If there was another provider i would have cancelled with telkom, I need to have this sorted out asap, I tried to contact them from the wkend only to either be cut-off or kept on too long. Last night someone answered and told me now i must wait up to 3 days for someone to assist. now my adsl doesnt last longer than 10 -15 sec then i loose signal. they quick to want there money every month. my number is *** or ***
