I'd agree that their customer service (or at least how they treat their customers in general) is shit, but as long as you stick to their ToS and don't deposit dirty bitcoin or withdraw bitcoin to whatever sites they have blacklisted--like gambling sites--you generally won't run into too many problems with straight buying/selling.

Beyond that, it depends on how much you value your anonymity.  If that's a concern then no exchange is going to be ideal, because all the ones accepting debit/credit cards require KYC.  In that case, I'd listen to some of the suggestions about P2P trading sites and even the Currency Exchange section on this forum (as long as you have a PayPal account or some other payment system you can link your bank account to).  That's still not anonymous, but it's better than an exchange.

You could also get cash from that credit or debit card and hit up a bitcoin ATM, as long as you don't mind paying the markup.  They're very convenient if you have one near you.
