ACCOUNT OUTSTANDING FOR ALMOST A YEAR!!!

Last year 2015 April, May and June (3 seperate invoices) we've sent Cucumbers to the Fruit & Veg in Richardsbay with absolute NO payment whatsoever for the Cucumbers. In this past year they had a couple of guys working in the accounts department and to everyone we sent several emails and calls about this outstanding invoices. The total amount outstanding is R7200! They asked for the signed invoices and statement, and we've sent it several times to different people working theRE with still NO result. We even took it to their head office, but still nothing. We are now sick and tired of waiting, because it is the worst business ever and will never ever do business with them again. If we don't receive payment by the end of this month March 2016, we have no other choice as to hand this account over. We are not a bank and want our money please.
