Poor service

Hi, (1.) with my order I received a mop that was substituted for what I ordered, I was not happy with this and I returned it...after the driver had left I noticed that the floro was not delivered. I called a few times and I mailed PnP, and had no satisfaction to date. I was told a credit would be processed, but nothing has come through yet...I am actually really disappointed with the service from PnP, and have since then not ordered online. (2), I received an email saying that I've a voucher that I can use since it was my birthday month, I went to PnP in Wynberg, but there was no voucher available, as the email stated...I left the print-out with the assistant that helped me, and I was told Lee Anne would get back to me, that was on 30/03/2015, I am still awaiting a response. This is really disappointing, and the response to all my calls have pathetic, and I feel quite disheartened with they way my queries have been dealt with.
