FNB eBucks terrible service

Very disappointed with eBucks and FNB. The service has been terrible.

I booked flights on my FNB app paying partly with eBucks and the rest with my credit card. The eBucks amount was subtracted from my balance and the credit card was credited. Soon after the credit card refunded my amount but the eBucks was not refunded, meaning that the flight I just booked was not actually booked. I then called eBucks travel and spoke to Lebo who said she would resolve my problem within the day. By midday I received no feedback so called back only to be told she was busy and would call back. Still no response.

Can someone at FNB please do their job and help me resolve this.
