How to cancel Gain by mail
Gather your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Gain can only act on a request it can match to an account.
Write your request
Postbye writes the letter in Turkish from our Turkish template, because Gain's address is in Turkey. It opens with the subject line “Konu: İptal Talebi – [your name]” and asks Gain to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Post it by certified mail to Gain in Beyoğlu, İstanbul, Turkey, using the exact address below, and note the tracking number.
Hold on to the receipt
Keep the tracking record with your copy of the letter. If Gain bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Gain cancellation letter goes
For a letter to Gain, use Fındıklı Çelebi Hamamı Sok. No:2-4, Ömer Avni Mah., Somer Han, 34427 Beyoğlu, İstanbul, Turkey.
The envelope is going to Beyoğlu, İstanbul, Turkey, so the postcode 34427 must be on the front.
The letter greets the reader with “İlgili Makama,”; your own details sit under the labels Hesap sahibi, Sistemdeki fatura adresi and Kayıtlı e-posta.

Before you cancel Gain, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
