Dakshin Haryana Bijli Vitran Nigam — Long electricity cuts and there are no particular timings

Hi, I am from NH-3, block G, NIT, Faridabad. In my area the electricity cuts are becoming extremely notorious. The cuts happen whenever the "officials" want, and are extremely long in time. Sometimes it happens for HOURS.
And, they also don't allow people to consume 600-700W of power for consecutive amount of time. I've tried this, I'm a 3d artist and my pc at full load takes about 500W, and rendering something takes full power, as long as my pc doesn't run on full load the cut doesn't happen and when it does run on full throttle for a consecutive time, the "all of a sudden" cut happens.

I need answers and apologies from the officials.
