refusing to reimburse monies owed

Edgars acounts dept johannesburg refuses to reimburse a credited amount owed to me, when I closed my account . It has now been four month and the amount is R79.00 is still forthcoming. How many other clientele are waiting for a reimbur*****t? I hand delivered the original documents that they required to the East Rand Mall branch and have followed up with various E MAIl and scanned in the docs. They still come up with the same excuse which is, ' Send us the following doc.",2015-09-07 08:59:14"""
