RCS is the worst

We are now in the third month, heading towards the fourth month. I am still awaiting my January and February payments to reflect. They are calling with no resolve. Demanding proof of payment to be emailed. I emailed, then received a call from another consultant. When explaining that I did email the proof of payment, the answer I received was that; "it was the other consultant". Therefore, everytime I receive a call, it's a new consultant. Meaning I will forever email the proof of payment. As my situation is handled by a new consultant now and then. It is frustrating to be called and told that I am in areas, whereas there is no month I have ever skipped.
