Hi, thank you for your message. I am sorry to hear about your situation. Unless there is a contract in place stating that you would be charged for the use of the pillow then they cannot charge you for this. Moreover,
Your landlord has a legal requirement to protect your deposit under one of the deposit schemes ( Deposit Protection Service (DPS) My Deposits. Tenancy Deposit Scheme (TDS). If they do not do so you can claim up to 3x the deposit for not putting in the scheme. You can read more about this here: https://england.shelter.org.uk/housing_advice/tenancy_deposits/tenancy_deposit_compensation_claims
I would advise the following steps:
1) make a formal complaint by writing a letter to your landlord.
Explain your problem and what you want them to do to solve it. You should include in your letter:
what you’re complaining about
what you want them to do about the problem
dates and times the problem took place
copies of any letters or emails between you and your landlord
Copy of the tenancy contract if applicable
2) If making a formal complaint to your landlord doesn't solve your problem you will need to make a complaint to your local council. You can find contact information for your local council here: https://www.gov.uk/find-local-council
3) As a last resort you will need to take the matter to court. You should also make a claim for the extra costs you have had to pay. I would advise that you find a solicitor in your area to represent you using one of the options below.
The solicitor will be able to weigh all the evidence before them and help you build a strong case. You can find a solicitor by using the law society find a solicitor link here: https://solicitors.lawsociety.org.uk/ You will be able to search by specialism and also town or postcode to find one near you.
