Failed at assisting me with they matter of a partially booked ticket

I booked return tickets from Port Elizabeth to Johannesburg on the 10th of May for my father and grandmother. As I was purchasing the tickets, two of the tickets which were the ones from PE to JHB couldn't grow through due to my daily limit. After increasing my daily limit, I then could not go back and process the second half of the booking as the eDreams website refreshed. I then proceeded to buy those tickets from scratch, A few days later I experienced money not reflecting in my account, I then went to the bank and was told there was a hold of funds for the tickets that never went through due to insufficient funds. Because the emails I got from eDreams only indicate that my booking was partially confirmed but doesn't state the prices, the bank than requested a receipt that shows that the purchase didn't go through from eDreams so they can release the hold from their side. I called eDreams the first time and they mentioned that they could see on their side that the booking was partially confirmed. I then asked for the receipt so I could provide it to my bank, and they gave me the run-around. A few days later, whenever I tried calling them their line would ring with no answer. I have now lost R2380 for tickets I never received all thanks to eDreams. What a ****ty service provider they are.
