I ordered online. They replaced some items with the others. On a day of delivery I was a little bit late for my slot. Driver came at the start of the slot and called me. I said that I am still on my way. He said that in that case he is going to bring delivery somwhere else and than same evening he will deliver again same day. Driver called after after half an hour and asked if I am at home yet. He said ' you know what I am not coming yet but when I come you have to come and pick the bags yourself'.I said that I can't he started yelling at me:' if you want me to come you come and get it yourself.' He just wouldn't stop yelling I had to hang up. AlsoI had to call customer service on 0800 number which is additional cost. Since tbere was no any other number in tbe email provided. Assistant was polite and said that he will get in touch with the branch and someone will call me back. I did not receive a call back so I called again myself and spoke to another very polite customer service assistant who informed that I have to arrange redelivery.She said that order did not change but when I saw order confirmation I noticed that some of the products were missing.I have to go on a website again. So ordering online did not save me time, made inconvenience and left bad impressions with their driver and not very truesthful customer service assistants. Also Waitrose take another payment again on redelivery for the whole order amount whilst refund takes 3-5 days.Which means that you pay twice for your order until you receive refund and redelivery was not available for the next day.
