is anyone else out there incredibly frustrated with the piss-poor response times to bugs and issues?

my client is beyond upset ...

not only am i billing him to recode the implementation to comply with these new API methods (and i am the second developer he has retained for this project, so this is the third time he's paying for a ZohoCRM implementation) ...

but when i open tickets on friday/monday and here it is wednesday with ****ZERO**** response, i just don't know what to tell him ...

frankly, i'd be pissed, too.
