Supertech — frequent breakdown of electricity

I am a resident of Eco Village 1 flat no :A1-418 ... May possibly i draw your kind attention about the frequent breakdowns of electricity in this society and the wonderful inconvenience it causes to the residents!
There are failures regarding electricity several times in a day.. Sometimes, the current is turned off for several hours in a very stretch.. the unannounced frequent breakdown of electricity is simply nightmarish.. Many times complaints have been lodged with your office but no permanent solution to this menace has been found!
I hope you would look into the matter at the earliest and redress my grievance.
