During the pandemic we have used the home delivery service exclusively as we are both in our sixties and were anxious about going out shopping. In general we got most of what we ordered. However, on numerous occasions they informed us on the delivery note they were out of stock of certain items - Guinness for example - which we found odd as we said we would have any form of Guinness as a substitution. Often the substitutes bore no resemblence to what we ordered. Further, many items were very near their sell by date. However, what really made us view Tesco in a poor light was the time when we had ordered our usual essentials and additional items as it was our anniversary and my wife's birthday and they just cancelled the delivery for 7pm at 5pm, leaving us completly stranded! They said that it was due to their system being down!! Surely a company as large as this would have contingency plans in place so they do not leave people, especially vulnerable people, stranded. Moreover, when my wife wrote to Tesco she stated that they would not be worried if they lost our custom as we are but small fish to a company of this size. She was correct! They did not reply!! So, hopefully by writing this review we might make a small splash in the Tesco pond and others can add to the ripples that might rock their boat.
