Worst and unqualified stuff at TFG

I have had the worst online customer service and shop customer service ever. I purchased an item at hi online on the 22 October 2018 and make a full payment using an egift card and my tfg account. To my surprise I received an email saying I must complete my payment when actually I did. I called in on the 23rd to find out what's going on and I was told the try account payment did not go through and I had to struggle to get that fixed as I was wasting my airtime to call the whole day until I figures out the stuff is clueless about their jobs and what they should do. I requested the funds to be returned so I can make the purchase again to make it easier for them. I make the same order again on the 24th and make a full payment and again the same emails and WhatsApp messages saying I must make payment when I already paid . I started becoming frustrated and called and this time they said the egift card did not go through as 2 people said that. The 3rd managed to see that both payments did get redeemed from my egift card and funds from my account reserved. To my surprise I still didn't receive a proof of payment or my order being processed instead I still get emails and WhatsApp messages that I have to pay. Then I became ****ed and called and they said I must wait an hour of which I did and nothing happened and I called again and they referred me to a store of which I did and to my disappointment the stuff was confused too. They called from the store and still could not solve my problem. So I have been trying to by a simple item for a while week with no luck and worst service by tfg. I then gave up and cancelled my order so I can get my money back. I was told over weekend I'll be contacted within 2 working days and it's 2 working days and no response. I always have to follow them around as if I'm the one causing this problem and using my airtime. Now I can't seem to get my refund of my money in my account and one from my egift card. So tell me tfg customer service what I must to do for you to take me serious. I want my money and your system fixed so I can successfully place my order. It's been a full week now with no help at all.
