bad service, no feedback, passing the buck

this is the first product that i bought from house and home and will be the last time, 3 weeks ago i took my amp in for them to repair and ever since then ive had to contact them and go there personally to find out what is happening, sunday 7/06/2015 i went in and spoke to the manager who didnt know himself what was going on and they had to feedback for me and i gave them a piece of my mind coz it still wasnt repaird and i had to come there all the time and wasnt the first time i spoke to the manager but still he couldnt say anyting and plus everyone was passing the buck and its always someone else busy with my repair and with my query, i am frustrated becuase now i went there again yesterday and now they telling me another story about it is fixed but i must bring my sound bar in for the electrician to test, i dont see why i must send my sound bar to where the electrician is based becuase they can come to house and home and test it. now again they tell me they will see what they can do. this looks like another 3 weeks of me having to go there or phone to find out what is happening. to me this just sounds to fishy for my liking and they are just trying to avoid
