Hi Carin,
I have quite a lot of experience in this regard.
I usually contact the ETQA manager directly – and together we follow the paper trail. In my experience it is usually either an administrative assistant that did not do his/her bit, the fact that they are mostly not at their desks doing what they are paid to do, on a course (they are forever attending courses) – and then the invoice is lying in an in-basket somewhere or has not been signed off. In some instances – we have found that it had nothing to do with the SETA – but rather the accounting/auditing firm (the financial function is usually contracted out) – that is at fault and not the SETA.
My advice – follow the paper trail – and determine exactly where/who the problem is. I usually get paid then.
Regards
Cecile
