Poor online service

I bought baby essentials at clicks online made the payment after a day they sent me an email that one of the items is not available so they gonna refund me I should choose how do I want to be refunded, which was they either sent me my money via banking account which was gonna take them 14-17 days for the funds to be put in my account which now gonna be to long and cause an inconvenience towards me or they load points to my clicks rewards card which was gonna take them less than 24hrs so I chose the points option cause this emergency essential for my child but to my suprise a week went by without the points and then when I received the order it was a totally wrong order tried calling but their lines were not working and they were not responding to my emails until I called again the following morning where I was told about the fact that there's only one staff member who was working under refunds so that's why my case was taking long .I was so frustrated that I demanded to speak to someone who can really assist cos my kid has run out and that I want my money back cos now I was forced to borrow money so I can purchase my child essentials and they put me through a guy called Darren who did put the points that was supposed to be put a week ago which I was grateful for that but now I'm still waiting for my refund and I feel it's not fair to wait for such a long time for my money especially if its them who are at fault here.
