Exchanges these days are having a fair share of complains. A lot of people are complaining about them. And why not will they complain. I have read many cases where there are people who have not received money in their bank accounts even after 40 days of submitting request. This was one of the complaint against Zebpay, a leading crypto currency exchange here.
Indeed this issue does exist. My entire point is that, in most cases the exchanges are not the problem. Given time the ones that can tackle the customer service needs (That never previously existed) by adding about a thousand people to staff just to handle the silly issues clogging the service ticket log. Patience will relieve a little stress. Getting fiat funds verified takes time, especially with the scrutiny that all the exchanges are facing currently. None of them were ready for the boom that occurred from late October to early December. That is why account creation was halted on almost all exchanges for some period of time over the past few months.
