The most appalling customer service I have ever experienced. I've been trying to give them money for four days, have spent over seven hours on hold so far (currently on hold again), their online banking site has poor functionality and just tells you to phone them, I've been hung up on twice and spoken to four members of staff in total, one who was apologetic and said the system was down and I should try again tomorrow, and the other three said they couldn't help me but would transfer me directly to a member of staff who could but just redirected my call to the bottom of the infernal being on hold queue. I strongly advise anyone to avoid Sainsburys products, plenty of alternatives out there
