Unsatisfied service from a unsatisfied customer

What an embarrassing service from Pick n Pay Online. I order my groceries from them every single month and most of the time I am 100% satisfied. – Of course we hit January and all hell breaks loose with them completely disorganized and all over the place. A Week late with my delivery, and when I phone them to follow-up I get told that there was an error from the warehouse side and that they promise it will be delivered today (that was yesterday). Now on the line with them for 20 min after my first attempt of holding on for 30 min, they have to phone me back because they can’t get through to the warehouse? I know it’s not the client care consultants fault and that’s not what I saying – but Pick n pay should have prepared for January’s orders – If you can’t deliver a specific date then don’t give it as an option and when you then tell they client that you promise a day for late delivery – keep to it! Thousands of Rands spending and now I have to cough up more just to cover the week I already lost in groceries…. Hopefully Pick n Pay can redeem their name?
