HI-FI CORPORATION BAD SERVICE

Hifi corp customer service is appalling to say the least made an online purchase on Monday evening and selected the wrong address. On Tuesday Moring I got through a very rude gentleman that told me it will not be possible to change my address and dropped the phone , I called back and came through a nice lady called Promise and said she will add notes for the address to be changed. Wednesday moring I login to check wheter it has been updated and It has not been , so I am so confused right now and would LIKE A REFUND SO I CAN BUY WHERE THEY ACTUALLY VALUE ME AS A CUSTOMER AND NOT SOME ****!!
