Q: A deposit of R4800 was given when a one year lease was signed. About three months after that, the lock on the sliding door was broken on a Saturday night, a locksmith was called and a quotation was given of R3070 to replace the lock because the locksmith did not have the correct lock with him, he only opened the broken lock, I was told only the next morning what happened, I suggested that a separate lock must be used on the front gate to secure the place and R3070 is much to spend on the replacing the broken lock. Now after 6 months the tenant decides to move out, from the R4800 deposit, R2800 was for commission for getting a new tenant, (this was in the lease agreement). I informed the tenant I will replace the broken lock. The total cost of it was R1000. The tenant was willing to pay the R3070 initially, must I reimburse the tenant the R1000 or must I claim the R2070 from them.

Q: On many websites when making an account for something or placing an order an option is necessary to be ticked that says, "Do you agree to the terms and conditions?" or "Have you read the terms and conditions?"
