Overall Bad Service that seems to only be getting worse

I have just been informed that my order that was supposed to be delivered at a pargo point latest 23rd November will only be delivered on Monday the 27th November as the Pargo Point was full and the courier took my order back for redelivery next week. This was not communicated to me until I made several calls today to enquire about my order. As a paying customer I don't understand why there are no systems in place to inform customers of such changes whether they are within your control or not. I am going on holiday today and now have to go shopping(and spend money I had not budgeted on) at the last minute as my holiday outfits form Spree will arrive 3 days after I have left for my trip. There are several Pargo Points all with less than 10km of each other, why could the orders not be delivered to another point and inform us customers of the challenge faced and the change. Is it not worse for paying customers to receive their orders 3 days later than when they were needed than to go get them timeously at an alternative point?
