Reliance Jio Infocomm — slow net speed, giving false assurance

Address:

Ernakulam, Kerala, 683561

My internet speed droped to 2g speed from month of april 2018. When complained they said it was coverage problem and said they will fix it within 120days from june 14th 2018. Till now, no change have been there in the speed and they are not acknowledging about the assurance they gave me. I have proof of their mail stating this. They cheated me by making me wait 120days and they didnt do anything.
