Pnp asap a disgrace

I ordered online the 6th July on pnp asap. I was over charged on donuts. R329.70 TO be exact. They did a refund and 3 weeks later I still dont have my refund. I email them, phone in and no one gets back to me. Everytime its a different story They say refund was done. Then im told it was not processed. Then.im told They canceled the order it will automatically refund me. I'm still waiting I phoned in now and the lady is so rude then she puts me on hold for 20 min. I hung up. I'm using more airtime than refund at this point. Totally disgusted that they take ur money and keep it. Poor poor service all round
