Short delivery with no refunds

I decided to make use of the online shopping service from Pick 'n Pay in April. My goods were delivered on time. Goods to the value of R151.98 (order ***) was delivered short and I was charged for this. I called the next morning as my delivery was at 8pm on the 29/04/15 to logged the short delivery. I was told that I would get refunded and till today no refund. I then decided to give them another chance and ordered again. My delivery was made on the 29/05/15(order ***) again I was short delivered to the value of R199.06. I phoned immediately and had a 11min call @ 15.34 with the call centre. This morning when I phoned to check the status of both my refunds I had to hear that my call was not logged. I had to go through another 11min and this time took the ref.no ***. Not sure if I would get a refund but would not shop online again from Pick 'n Pay, I also mailed the online store and to date no feedback.
