Worst online shopping experience ever!!!!

I have placed an online order to the value of R6679.57 but only received the value of R3990.23. This was the first time I ever used this method and I initially found it very user friendly. I have contacted the two customer care numbers as well as all numbers on the website since yesterday 9:30am, just after I received my half delivery. Each time I do not hold on for less than 10 minutes without answer. I have logged a query online and also sent an email to the online shopping email. I requested someone to call me to explain the following. 1) Why am I allowed to select stock on the website if it is not going to be delivered? 2) Why am I not informed of the non delivery of almost half of the items? 3) Why is the pending amount on our credit card more than what we received? 5) I have also requested the invoice to be made out to our Company name and surprise surprise it was made out to my name. 6) Who do I contact since no one answers a phone?<br> Unfortunately PnP are one of few stores to offer online shopping but since they can't even do it properly what is the point. I would not recommend anyone to use it. Worst part of all is that we are based in JHB, with plenty PnP's around.
