NO CUSTOMER SERVICE

I purchased a Flex Adventures TW95 - 95L 12/220V Plastic Dual Zone Fridge/Freezer which was delivered on Thursday (14 November ) late afternoon. We opened it on Friday (15 November) before we left for Jeffreys Bay to visit the kids. I booked a return when we arrived at our destination and they told me that it will be collected on Monday (18 November) It has not been collected, I called yesterday just before 5 and it was said that they will contact the courier company. Nothing. This morning I called again, and once again my query is escalated without any feedback or answer as to when I this collection will happen. I bought this fridge / freezer as we are leaving on holiday on 23 November and need the fridge for our perishable which we will be taking with us. At this rate I will not have my replacement as this has not been collected yet. We are not there and I have to rely on friends to be there to hand the item and receive the new one from them and they now need to wait around as no one can give me an answer. I urgently need an answer as to when this collection will happen and if I will have my new item by Friday as we are leaving on Saturday and I need this.
