oh no, customer support of blockchain.info sucks. literally sucks, never go and talk with them
Most of the customer supports are crap. Luckily, I rarely have to deal with them or avoid them completely. Tho, I've never had the opportunity or reason to contact blockchains.info support, but I've never had any problems with that whatsoever that would require the need of customer support. Maybe that's just some special, "delicate", problem because I know people from my country having problem with banks and bitcoin exhanges where the bank would actually lock their accounts.
