Debian Configuration :: VPN PPTP Load On Start And Route All Traffic Through Ppp0?

I am in serious situation involving PPTP protocol VPN in Debian 8 Jessie stable. I recently became a paid VPN subscriber. Using PPTP; Is there a way to automatically route all traffic through ppp0? Im getting the vpn service killed (ip address goes back to normal unmasked state) whenever there is a power outage (modem reset) and there are alot of those where I live, Im going to get astabilizer and I need a software solution for the situation as well. Theres gotta be a way to route all traffic through the VPN route ppp0 . I tried adding persist and maxfail 0 to the pptp config file but it did not do what i wanted.

Here's my peer configuration file :

pty "pptp blabla.net --nolaunchpppd"
name blablabla
password blablabla
remotename PPTP
file /etc/ppp/options.pptp
require-mppe-128
refuse-eap noauth
persist
maxfail 0

On a second note, its clear to add that I basically need a way to also auto load the line

pppd call blabla.net
and
route add default dev ppp0

On system startup by default so the computer does not use "Wired" connection ^at all^ when not through ppp0. Any other way of not losing VPN anonymity ever due to hardware malfunction.

Is there a way to do this? Ive looked on the net and everything seems like its either from the nineties or can fry my pc , Im no debian expert, less than a year at linux..

Need it to use wired only if ppp0 is being used so if its no vpn, no connection at all period,
