Grabitall = Grab-problems - losing money

I placed an order on 25.09.2020 for the One Step Hair Dryer at Grabitall online. The payment was done immediately for my order. On 30.09.2020 I received an email my order has been packed and ready for delivery. Delivery was on 01.10.2020, however, I was not at home for that weekend and my parents received it on my behalf. On Monday morning, 05.10.2020, I wanted to use it, so very excited about my dryer I plugged it in and switched it on, only to find that it is not working. The handle gets very hot but the brush not. I emailed them explaining the situation and they fetched it 07.10.2020 and also replaced it with another one. I opened it and plugged it in. As soon as I switched it on there was a lot of smoke coming out, almost as if something burned. Again I emailed them advising that again it is not working and I would now like a refund. They came and fetched the faulty unit 13.10.2020. From this date I have been sending emails regarding my refund. They asked for banking details and it was given to them, but up until now I am still waiting for my refund. They told me it will reflect in my account 21.10.2020. Today is 27.10.2020. There is no contact details where I can phone them. I have to communicate via email and they are not responding. This is really pathetic service and they are not keeping to their policy online. I do not know if anyone else experienced this type of service but please think twice ordering from this site.
