Shocking online service from pick n pay online

I have not ordered from Pick n Pay online services in quite some months due to my past three experiences being ********** in terms of incorrect items being delivered and not receiving sufficient refunds for items undelivered. Eventually I became tired of following up on my refunds, so I just left it. I decided to give the online ordering another try and am extremely regretful of doing so. I placed an order on Monday evening for delivery today, Wednesday 20th November. The items arrived this morning and it was the worse order I have received to date from Pick n Pay. There was an additional 7 items that were not on my original order that arrived and a number of items not delivered as well as items that were substituted that are hat you would expect from a substitute, such as substituting a can of whipped cream for fresh whipping cream.

Upon returning items and requesting a refund, I was told that it would take between 5 - 7 working days to receive my refund. I had budgeted very specifically for these items and must wait up to 7 working days for my refund so that I can now get into my car and drive to the shop to buy the items that were undelivered. Pardon my irritation, but surely this defeats the whole purpose of online shopping!!!!! The service and follow up received from Pick n Pay online is absolutely unprofessional and poor. This is the last time that I will shop here as this is clearly a trend that I am sure am not the only victim to. Four orders and four consecutive errors!
