Shocking service from Pick n Pay online shoppung

After many years of doing online shopping at Pick n Pay, I have now come to realise that incompetency is an understatement. I ordered my normal monthly order for last week Friday between 9-10am. The order arrived on Saturday lunchtime to a closed business!! I contacted the department concerned who admitted they have developed a problem. HALF of my order then arrived on Tuesday and although my account has been debited, my other half has not arrived. Numerous phone calls and emails to no avail. I will be taking this further and Pick n Pay will never see me again!!
