He made full payment in January and informed my boss that he would return in the next two days to collect the bags.
However, he did not show up until four months later.

According to my Boss the seller, after waiting for several weeks without hearing from the customer several times and his line was not going through and the price of cement currently have increased significantly in the market. When the man finally returned after four months being 3 days ago to carry his cement, the seller my Boss refused to release the bags.

He explained that the current price had risen to ₦13,000 per bag and demanded an additional ₦100,000 before the man could take the cement.

The man was shocked and 4ngry. He insisted that he had already paid in full and was not going to add any extra money. “I paid you completely four months ago,” he argued. “I have my receipt .

You cannot change the terms now just because the market price has gone up.”The seller my Boss remained firm, insisting he must pay the balance.

The buyer came with police and arrested my boss. In your own view who is at fault?
