Rototank refuses to refund me for 2 months.

I bought a tank and a pump in October 2025 at Rototank Boksburg and unfortunately I had to return it. I have been waiting for my refund to date 23 December 2025. They do not care or give any update on the status. I must call them all the time and every time they tell about head office still processing it. There is zero customer care and urgency. I am really disappointed in their services
