Netstar battery drainage!not getting assistance from Netstar

I have an issue with Netstar, My car which was 12 months old at the time started to have battery draininage issues and Toyota adviser to check with them. Getting a technician to assist has been a nightmare after calling on 5 seperate occasions and each time ending with either a supervisor who promises to call me back, a support agent promising to call me back or the line dropping after being on hold. Whenever I take it upon myself to jumpstart the battery I am given a ridiculous waiting period and by the time they arrive the car is dead again and they can simply not work on it. After multiple attempts of reaching out to get them to devise a plan on tackling this from a technical perspective I still have no answer but a car that has been flat for 3 weeks.This is totally unacceptable.I wouldnt recommend working with this company
