Vinted complaint: uncleared money in my account

Hi ,

I started selling on vinted for sometime now with no issues until I have decided to put some of the money I made in to one my accounts which I haven’t used for sometime to save them so I have transferred £635.88 on the 11/04/2023 and again £42.80 on the 13/04/2023 but unfortunately the money didn’t go through so I contacted vinted and they advised to check with my bank , the bank couldn’t track them and asked for some details which I have sent to vinted and asked for these information as these are a proof and the only way the bank can track them but unfortunately vinted was not very helpful and each time I reach them they ask for more time and as a single mum I am struggling and really need the money now . All the bank wanted was ARN number which is a 23digit and FPID which number depends on their bank also was it a card payment or faster payment, I am now thinking of taking this further if I don’t receive the answers.
My name on vinted zara-zara1985
Kind regards
