Sai World Link Cable Network Guru sadan Ganesh Nagar Dombivali West, Mumbai City, Maharashtra, 421202

Hello sir/madam,

I have been using the tv cable service of hathway (Sai world link cable network) since 2017. Every month i was paying 330 rs for there service. Now i observed that they are taking extra charges during the filling of renewal form (As per trai regulation). Form has been submitted manually today[protected] in there dombivali west office. Before submitting the form i have checked calculated amount against the subscribed channel in http://www.hathway.com/Digital/OnlinePlanRequestForm
Where total amount was around the 250 rs. Including the gst 44 rs.
When i submitted the manual form they took to me 313 rs.
They were forcing me to pay 313 rs. They also took to me extra charge on feb-2019 as 380rs. But actual should be 330. Kindly do the needful.
