********* business practices

a long overdue account dispute with air liquid never resolved , first of all as a partner with air liquid we did not expect them to ***** our business the proceed to still charge us for cylinders taken by them , last month we mistakenly paid money that was meant to someone else into their account for the amount of R50 000 which they are now refusing to refund even if they take the disputed amount off they would still owe us money. I have mailed them and tried to reverse the payment yet they still refusing to respond.
