Is this how bytes treats employees that resign

I would like to report my former manager (Johan Haasbroek) for not really caring about his employees.I recently resigned from my previous company and served my last day on the 13th October 2015.Today is the 23rd of October and I still haven't been updated as to when exactly I should expect my final salary.I have sent emails to my former manager and it seems he is reluctant to ensure that my salary is paid to me in due time to pay my rent as well as buy food for my 2month old son.This morning,after sending a heated mail to his manager,he responded by saying that I never sent him a mail when I clearly did.I am a very disappointed ex-employee,as I was under the impression that serving my 30days notice period,would prevent such issues from arising.HR's Nomfundo Khumalo,went to the extent of telling me that I will only receive my salary on the 30th October,because payouts only occur on Fridays and I was late in submission.I would like to know why or how is it that salaries can be paid on any other day of the week when payday is not on a Friday.I would like for Bytes to review their processes (If it is a Bytes process)),and ensure that future employees are protected from such instances.
