One of your drivers was really inconsideratly parked in my estate, along 3 permit bays there is plenty of visitor parking around where he parked. I waited for him to return and he laughed at the situation.  I have an allocated numbered bay, if you dont park in your allocated bay you will get a parking ticket. I truely believe some of their delivery drivers need extra training in parking and even customer service I am also unsatisfied at how my complaint had been dealt with by their online chat staff and also over the phone by the contact centre which was lacking any empathy or solution to this issue. Very disappointed Sainsburys.
