Poor service

I called requesting for my app logging details and they said that they will send it yesterday and they never did. I device has been faulty and since they said that they would make an appointment to come check it or change it and they did nothing. Yesterday I asked to be taken to the emergency department to check why everytime when I take out my battery I don't get any call or alert and they said that they were taking me to the maintenance room and they dropped my call. I pay my premiums every month and this is the kind of service I get. Please give me the service that I'm paying for.
