Bad service and so frustrated!!

13 items were missing from my online shopping delivery. The delivered items were checked with the driver and on the delivery invoice that was given back to the driver, a note was made of the missing items. The driver signed my copy as proof that the items were not delivered. I sent Pick n Pay a follow up e-mail on Tuesday after receiving no feedback from them. For Pick n Pay it is more important to request information again that was already in the e-mail I sent them than to concentrate on the problem. I even attached the proof where the driver signed that there were 13 items missing. Now, another day later still no response from Pick n Pay. Pick n Pay is now not contactable as the inbox is full. Both my messages I sent today was returned as undelivered.

I just want to know how is Pick n Pay going to solve this issue as they have taken the money from my account for the 13 items.
