Taskbucks fraud. Review on Taskbucks

I am using taskbuck app since january 2016. At first sight it appears to me a very good app for earning and transferring my earnings to paytm account. First time when I installed taskbuck it gives me many apps or tasks to earn but after that it stop giving new tasks it gives 1-2 apps in one week after 2-3 weeks. I have earned approx ₹400 after using it for 8 months that is weird. At first I when I transferred my earnings to paytm there were no charges. But after 2-3 months of use it start charges for transfer 3 for ₹25. After that 4 months ago it didnot give me the option of transfer. Its option gone anywhere. Now I have only option to recharge my own registered no. with the plans given by taskbucks. I wanted to contact many times with taskbuck regarding this , I mailed them many times but I hadnot got any response from them yet. Now my earnings of almost ₹170 is stuck in this app which I am unable to use. So in my opinion its only a fraud and fake app which in starting to attract users gives earning but after that stop everything. In my opinion it is also a time killing because not at point terms it seems good to make ₹400 in 8 month of which ₹170 is still stuck in the app. So I recommend others not to use this app. Thanks.
