After a failed delivery on first attempt they Ignored alternate delivery instructions for next two attempts that would have ensured success. On complaining they reluctantly accepted fault and I was then told that exceptionally they would attempt delivery a fourth time and that a manager would call me. Neither happened and I am very sure that I was being lied to by the call handler. Further complaints were then ignored and they refused to accept that the fourth delivery had been promised despite me sending transcripts of the web chat. I will make all efforts to avoid ever having to use them again and I would advise others to do the same.
