HiFi Corp horrible service

I purchased a PA system at the end of November 2017. It was used only three times. I tried switching it on Yesterday and it just would not work. I called the call center and spoke to Zodwa, who advised that someone will contact me within 24 hours to collect the item from me. I called back this morning because i did not get a call from anyone. I spoke to three woman who could not assist me. They hung up on my three times. On my forth call, i got to speak to Zodwa who advises that i have to take it to my nearest store. I purchased this item online and my nearest store is almost two hours drive. I also paid for the courier cost. Now i must pay to take it to the store and collect it once it is repaired or replaced. This is not fair that HiFi Corp refuses to assist with a defective product that they are selling. The product is a SANSUI PORTABLE PA SPEAKER PPA901 that i paid R1579.00 for incl courier cost. I will not accept the service received from HiFi Corp. As per the consumer protection act i demand that the product be picked up and a full refund be given to me for firstly a poor quality product and horrible service
