HiFi Corp has the worst customer service - zero empathy!

I bought a fridge online at HiFi Corporation during Black Friday. They delivered the fridge on 1 December, and after inspection on the same day, I sent an email requesting an exchange because the product I had received had dents and scratches on it, looking like it was a fridge that has been placed on display at their floor. Today marks two weeks and HiFi Corporation is yet to fulfil their promise of collecting the fridge I am not satisfied with and bringing one that is of quality. The only thing I get every single day is "sorry for the inconvenience, ma'am" but no action. Do not believe the lies written on their website about being able to return their products if you are unsatisfied within the 1st 7 days of receiving their stuff. I have communicated that I am going on leave soon, therefore they should act swiftly but they do not care a damn. The biggest mistake I ever made was trusting them. Do not do it! They have the worst customer service! They have a warehouse here in Gqeberha but they're struggling with giving me a new fridge, how? I am in the customer services field myself and I know for sure that they don't care. If they did care about customers, they would've acted by now. I've had to throw away the fridge items I had because they became spoiled. A waste of money! If you don't want any drama in your life, do not ever buy from them! I made the mistake of buying before reading reviews and I regret that.
