RARU - SERVICE DELIVERY ISSUES

I had some great experiences with RARU up until last year when they cancelled two orders weeks into the transaction. Since I had heard that refunds were not forthecoming from other users and was told by a RARU staff member that refunds could take a few weeks, I opted for non import items (The RARU staff member also said they have had a big issue with imports for some time now). I received them within the specified time. My quandry now is that the item I so desperately want can now be ordered with a 15-20 day delivery time from the UK. Why can they not be like Amazon and only bill you once the item is being prepared for dispatch or make it a cash on delivery transaction for repeat customers? I think Takealot has a COD option. We are currently paying for goods upfront that only arrive months later or never at all.
