From last couple of weeks the speed of internet is getting continuously decreased. Before that the speed was so good! But nowadays its not even good! If you could resolve this issue, it would be great! Because i want to be with network provider only! My address is 19-b, sainath society, opp. S. T. Depot, mandvi, dist - surat, 394160. Please solve this issue of mine as quickly as possible! And if you can't do it, then there is no other option for me than to go to other network provider!
