If this is a new apartment, then this repairing is reasonable. If it were old, then this repair was hostile and up to you how you are going to fight.
Here is something you can think:
1) For those items you requested to repair, but not done in your leasing term. It is called deferred maintenance and is a kind of damage to your lease interests, so you could ask for the compensation or partial refund for your rent;
2) For the repaired Cabinet, your share should be prorated, the normal residence’s depreciation period is 27 ½ year, at least you could prorate your share according to this period;
3) Let them show you the receipt for that cabinet repair; and get price quote from other contracts
4) Write a letter to the leasing office to address your argument and propose a solution
5) If they sent your debt to collect agency before they answered your letter, that is kind harassment, and you could use it as one argument in the court
