Clicks mishaps

I had a very bad experience with Clicks via their Clicks app. I bought electricity on 1 September but never received it. When I contacted them I was told: Due to a technical issue Easypay did not receive the payment (but was definitely deducted from my bank account) and that I have one of two choices:

Option 1 Should you wish to be refunded, Please note EFT refunds take 7-14 working days to reflect into your account . Option 2 We could offer you a refund in the form of a cash back reward loaded to your Clicks ClubCard in 24 hours. I am very upset because the R1500 I used are for my monthly electricity but now Clicks wants to force me to i either wait 3 weeks or take a cashback voucher that will only benefit them! Please people rather buy your electricity from a reputable provider but stay away from Clicks. Where am I suppose to get electricity money till they sort this nonsense out!!!!
