They ****med me my deposited money.

Accumarkets ****med me my deposited money. They claim they didn't receive my deposit while I gave them proof of payment. They insisted that I should tell my bank to find out where exactly did my money go. Despite the fact that they have a proof payment from the Bank they still refusing to clear my deposited amount. I used a OZOW deposit method. The bank says the money was successfully deposited to Accumarkets.
