I want Payment of what is due to me.

I transported food to 8 schools at Sinthumule area (Louise Trichardt) called Thepe area from Polokwane for MML Foods company based in Polokwane in month of January and February 2018 using my truck and submitted invoices to MML Foods. Till today the company did not pay me the full amount .Last time they paid was in March just part of the bill since then never pay me at all.Each time I enquirer they promise to pay same day I complained or next week it never happen we are now in July 2018.

When I call to enquirer they ignore me by saying people who deal with payments are busy or not in.My experience with them is that they are very unreliable, unprofessional and regret the day I agreed to assist them when they contact me for assistant.I would have appreciated to be told the truth why am i not getting paid. I am writing this because i lost hope that I will be paid at all.I even send the email to the CEO of the company who never respond. The lesson is that being a small business trying to do business with the big business they will ride over you till you are completely out of the business.

Please help me!!! how do i get paid what is due to me from this company.
