I will tell you why you should never choose ZbigZ
Zbigz disconnects frquently.
ZbigZ corrupts the files that you download that you will have to download from the beginning
ZbigZ cheats customers by taking their money and not giving them premium . I paid Rs 360 for premium. But in the end, I never got a premuim account. It happened to me thrice. The third time I did it so as to give ZbigZ another chance.
Their primary payment gateway is fraudulent. Their payment site is 365premium. Never buy anything from them.
I think I have given you enough reasons to not buy ZbigZ. Always go for other alternatives like seedr.cc. Sure, it is a bit more expensive. But it is always worth the price.
