Incorrect amounts debited from account - 13+ days waiting for refunds

What a terrible experience.. I will definitely not recommend the online order system with a voucher. I purchased a Discovery voucher for Netflorist to purchase a fathersday gift - biggest mistake ever. When I placed the order and entered the voucher, I got my otp from my bank confirming the difference, but the full amount was then debited from my account. Queried this and Netflorist confirmed they will refund, I should try again the next day.. 2nd biggest mistake - again the full amount was debited from my account. Phoned my bank, who advised the error is with Netflorist and they would need to refund. This all happened on 09 and 10 June 2021. Till date I have only received 1 refund. I have to constantly phone back every 2 / 3 days just to hear the same feedback. Refund will definitely be processed and will reflect within 2 to 3 day it has now been a total of 13 working days. My telephone charges are starting to cost me more than the money they owe me. And to top it all, you can not speak to finance and you are also unable to speak to a manager. Save yourself the hassle and don't order from them.
