Paxi at PEP gives your contact details to telemarketer without permission

In general I don't have a problem with PEP. Yesterday I had to collect a Paxi package at one of the PEP stores and the cashier asked for my details (which I normally don't just give out) in order for me to receive my package. Since this morning I have been bombarded with telesales from Multichoice and DSTV. And when I asked who gave them my number, all they said was it was added to their database yesterday (the day I collected the package and had to give my details).

So this 1 star is for PEP for selling my personal data to a third party without my permission.
