Pathetic service

I phoned Samsung call center as I have a problem with my Samsung Tumble dryer. I was told to phone their repair center as my machine is out of warranty . Firstly I was given the number as *** , which incedently is incorrect. The number is ***. I spoke to the person Melany and she confirmed that somebody would contact me on 2015-05-15 between 09h00 and 10h00 to confirm when they will be able to come to my house to see to my tumble dryer. I waited for the call untill app 13h00 and phoned again as no person has called me yet. Melany told me to phone the repair tech (Sam) and told her to let him call me . I'm still waiting for a call from any person as to when they will be attending to my problem .
