Spark Broadband — Installation done late and frequent internet disconnection

Address:	Mumbai City, Maharashtra
Website:	www.sparkbroadband.com/

I registered on 10 August 2015. and they promised to install by 12 August 2015. After a series of calls and complaints, they did installation on 18 August 2015.
But after connection, there is frequent disconnection of internet and the technician dont come even after repeated calls and complaint registration. The customer care is pretty useless as they dont have visibility and only work for salary like bunch of . And neither they trasnfer the call to the Higher Authority.
