Falsely accused of *****

I was talking to a client wanting to buy some collectable toys from me all was set and sorted i send him all my info with a bank letter and photo of i.d insuring that he has all my person details and that i have all his delivery details everything was set and sorted the client made a very generous offer i asked if he is sure that amount felt to much and he said that the amount was fair for the product we agreed that he would do the payment the next morning then i can ship it off and send him the waybill all hood and granted after agreement the client made payment for the product i contacted him and notified hom of the sms that said payment was **** to me all good i packed the product 6am i was ready to load funds to my pudo so i can take the boxes and deposit it by pudo but i could not funds loaded to my pudo . I contacted the bank where a consultant me and informed that the client of the 8000 deposit was the one who placed the hold on my account i asked her what for she wasnt sure but gave me contact details and case nr ,, i then contacted the ***** department attached in the mail explaining i didnt commit anything *****ulent along with screenshots of the complete conversation between me and the client i then asked if they could remove the hold as they have proof im innocent but no nothing happened iv lost 5 potential buyers sins this hold because they cant eft to me ! The bank advised i talk to the client and ask to withdraw ***** case the client ignore me completely , i feel like my bank also just ignoring me because with physical proof of innocence they didnt want to assist by removing the hold . I told the bank he could have just said he changed his mind and i would fully refund him instead of preventing me from making any income now because the clients cant eft to me what more can i do
