Poor customer service and bad sales management

I used to buy furniture at Joy Furniture in Rustenburg. The branch closed and they now operate from Pretoria. I bought a bed over the internet in August 2017 and they delivered on time but had the wrong base with damaged leather. I wrote all my issues on their delivery note and even informed them over the phone. They promised that they will collect the scratched leather piece when they come to deliver the correct base. I had to follow up 3 times before the base was delivered and the piece taken back in October 2017. I kept on calling the shop to find out when the piece would be returned and they kept on telling stories when they would deliver. They delivered in February 2018 after I sent some hash emails but the piece was worse than the initial damages. I took pictures, did not accept the delivery and visited the shop the following day. They promised to replace the bed and would call me on Monday morning regarding the process. I received no call until I sent a lady named Marzanne an email to complain about the whole situation. She promised over the mail to have the issue resolved in 1 week. I am now in my 4th week waiting for feedback. They do not respond to emails anymore and their telephone lines are out of service. If anyone has an advice please help me out.
