Faulty fridge and bad service

I bought a fridge online and whilst using it I was not happy so I requested a return within a month of buying it. I never got help, been calling their call center number n they've been transferring me to amanzimtoti where they were not even helping me. Been sent from pillar to post others kept on saying they were offline n promise to get back to me from the 4th of this month to date no help. Someone said they will send hisense technician to check while someone asked me to wrap it up and prepare it for collection I'm confused and I already bought a new one at makro again stuck with 2 fridges and no space in the house. I'm so frustrated and need a refund.
