Poor service on delivery of item and no support from call Centre or emails. Facebook support is the worse

I bought a fridge online due to breakage of mine. I paid the 9th of June 2023 on Saturday the 10 June I got a SMS about the delivery I phoned the number and was cut of and the 11th time I was able to arrange with them for delivery on the 15th. I got and confirmation SMS to say delivery will be the 15th. I arrange with my work to be at home the 15th. They then phone me at 12:03 Monday 12 June 2023 that they are at my home to deliver fridge. I informed that I arrange for the 15th and that I am at work. Then the 14th I got an SMS 6:59 to confirm delivery for the 15th. Tuesday at 14:19 i got an SMS that delivery will be the 17th. I phone them again only being able to complete conversation after the 5th try, They lodge a query and i explained that my old fridge is being collected the 15th by the insurance. I have no other day to take off. They said they will escalate this to warehouse. Since then no communication or joy from them. Phone this morning at 8:29 and still the same story and no change. I ask to speak to a manager where I was informed it would not help. So it only tells me that all staff in Hifi Corporation is in charge an no superiors over them if there is queries. If asked that they then arrange that delivery be Saturday early as I have a function I was just informed that I had to be at home till delivery take place. They have my money and my fridge but I do not know where it is. I cant get my money back as there refunds take 10 working days so it is helpless and they just don't care take your money and then you have to suffer to get your items. Will never use them again second time that they fooled me and will not allow this again and will warn a lot of people.
