Damaged item

I ordered a double door fridge from Rentoza on the 16 of March my order only came to me on the 25th of April I had to manage without a fridge I opened the fridge on the 26th of April only to see the fridge is damaged it's not getting cold and I'm so beyond frustrated to get someone to sort it out, they responses are so robotic but let it come to payment that is something they very good at. So what must I do now wait another month guys can you be helpful and have a sense of urgency this is a service you guys render however the customer satisfaction is very bad.
