TFG Online Service Bad expirience.

I bought sneakers online at TGF and used my Nedbank card to pay, unfortunately TFG could not source the sneakers and I was told they will refund my money back to my card. All this happened on first week of June. I waitied and waited because I was advised money will be on my account within 14 days. 14 days passed and I called their online contact center, a guys by the name of Storm Marshal said they did not get the money but I must go to my bank (Nedbank) to ask them to reverse the money. I did that and unfortunaely Nedbank could not assist me and they wanted to charge me R350. oo for the reversal which they adviced that they could not gurantee that the money will be reversed. I send an email to Storm and his online refund department with the response from Nedbank, which said they should contat the bank, it is now end of June I send them emails daily and no one is responding to me. Someone could have received my fund, why they where sourcing sneakers if they did not received the money.
