False claims of non payment via my employer

I do not want to give any starts but apparently it is required. After submission of proof of payment, Woolworths deemed it good to send an email via my employer with the heading reading "that payment on you Woolworths *** Card is still awaited."

Apparently the Popi-Act is not applicable to Woolworths and all of this, AFTER payment was already made, a phone call from a very rude Gloria (miss high-and might) where I confirmed that payment was made, and AFTER PROOF of payment has been submitted.

Suppose they are working on Christmas-bonuses. Still not reason enough to send such an email via my employer.

I will be awaiting an apology email.
