Forever late payments. TWF disrespect service providers.

I have been working with TWF as service provider in the hospitality industry for many years. Forever it has been a struggle to get paid on time. The agreement is 30 days. TWF however extend this to 90 days plus. You will seldom be paid more than 30% of outstanding money's.. I see Christiaan's name being mentioned in other reviews. Christiaan has not once answered any of my E mails. TWF is again late, more than 60 days of statement, on my payment. Promises of payment does not materialize. Emails are not rep**** to... It seems as if staff are encouraged to perform payment as late as possible. I would appreciate a value statement from TWF.
