No payment made

I worked on on orshaircare in edenvale for a makeup promotion they had for their year end function. It has passed over a week without my payment and was told that they made a payment with an unknown agency i was with.I worked with a friend of mine and when i ask her about the payment she said also she didnt receive it.im lost for words and in shock that a big brand like this would operate in this manner.i would still like my funds because its money i worked hard for.
