Incompetence House and Home Rustenburg

I bought a refrigerator from House and Home and January 16th I reported it was not working. Hisense sent a technician and I have since been waiting for House and Home to collect and replace the refrigerator. I have since bought a new refrigerator as House and Home has failed to replace or to refund me. They keep on saying that Hisense has not given them a credit, I had to call Hisense to request them the credit. I emailed them the slip(same slip I sent Hisense) now they say they can't process without the original slip. I have been 4 times to the store and I cannot keep on taking tome off to go to House and Home. They are using delay tactics and they are making me angry. If they did their job I wouldn't have to run around like I am doing.
