SC Product Options

Used to be a good plugin until today. My product option on my website suddenly not working. It was all ok all the while and we have zero clue what happened. I didn't notice this app was no longer under Bold until this happened. My team and I were trying to contact their support via email, chat, and any way we could. They greet you but when asking about our problem, they do not reply at all. My site relies heavily on this app and they are highly unprofessional when dealing with customers. This is not a free plugin so I do expect someone can help me solve the problem not creating a headache for me. Not recommend for anyone.
