Hathway / Gujarat Telelink [GTPL] — issue of speed and no response on complaint

Address:

Ahmedabad, Gujarat

Hello respective,
I'd like to inform you that from few days my internet connection is not working between 1pm to 6pm. My service provider is a well known company gtpl.
After complaining in company they always told us that our issue will be resolved in 24 hours. But the same problem happen again and again. They give us the same answer every time. I have paid for paid for 40 mbps and i can't even feel 20 mbps of speed. So it is a speed issue which they are not even gave attention on complaining.
So i'm kindly requesting you to take action on this.
