Disgusting Service Call.

I recently call LG to book a service call for a washing machine, the first person that took the call, Mitchell sounded efficient, however after four days I called back only to discover nothing had been booked and so I went through the process once again. This time I am sent a reference number and advised that a technician would call me to set up the appointment. Two days later I receive the call from the technician Charlie, he is at my premises and wants to gain entry to carry out the work. I advised him that I am at work during the day and that he needs to advise what day he can carry out the repairs to which he replies he will call me back later. The very next day I get another call from the access control at my residence advising that Charlie wants to gain entry to carry out the service call. Are these people just plain stupid that they do not understand that I work during the day and as per their call centre the technician is going to call to set up an appointment and not just arrive. So Charlie has left as there is no one at home and has promised to call me later, I doubt that will happen. Absolutely disgusting customer service.
