Record insert in account module suddenly stopped working

Record insert in account module suddenly stopped working

hence the ZOHO response for past 3 days and doesn't fix it yet..

at first the record was inserting good, but update was not working hence i have contacted support to check and help us for the update process, but when they started their support process the record itself is stopped inserting and they ask me to check with my code which was already working 

that too with silly solutions like - use " instead of ' and more solutions kinda the same 

i don't know whom to communicate regarding this issue
