Felix and Oberlisk have continued with a successful photography business, using drones. They have decided to lease a small office and found that Better Building Company Ltd. (BBC) owns a block of offices which it leases to tenants. Since January 1, 2018 BBC have contracted with Property Management Company Ltd. (PMC) to manage the leasing of the shops on their behalf. Recently they became unhappy with the service provided by PMC and terminated their agreement, sending letters to all tenants informing them of this. However, Felix and Oberlisk did not receive this information because their letter was lost in the mail. As a result at the end of the month they paid their rent of $3,000 to PMC as always. Unfortunately PMC has now closed and after an extensive search, its directors and the money, cannot be located. The lease of the offices is now managed by Alfred Bert and the sign at the main entrance to the property with the offices now clearly shows this, although it did take BBC seven weeks after the termination of PMC to replace PMC's name. BBC claims that Felix and Oberlisk still owe them the rent of $3,000 and the payment they made to PMC is Felix and Oberlisk's loss. Felix and Oberlisk disagree.
