Customer service!!

I have returned a faulty screen in the beginning of march and have not recieved any feedback up until i queried a month later, during this whole process they have send my screen away and no one knows where it is, it is about 5 MONTHS now with a problem they could have told me to report manually. NB they are not good at problem solving many of them have asked me the same questions over and over so there is minimal internal communication.
