Raru refund queue

I don't like to write a bad review nor do i like to say anything negative but i wish to share my experience with Raru. I ordered a graphics card on just 1st. was notified that it would take 10 working days, after two weeks the 10 days had expired and my order status was "in progress" I sent them an email to cancel the items as no progress in two weeks is already a long wait. they responded quickly and said they have requested a refund. i am still awaiting my refund and its the 3rd of August. Over a month and they still sitting with my R13000 in their bank account. its a lot of money to do without for over a month. i sent them another email and they say i am in a refund queue than it will take 15 working days tp process or even longer. Why do i have to wait three weeks just for them to process a refund. I payed them immediately so why cant they refund me immediately. This is the worst online service that i have ever experienced and i will take my money elsewhere next time. Be warned this is how they treat their customers.
