Means of contract termination (Switzerland)
<p>The Swiss company Yallo (telecommunication) does not accept written contract terminations (see <a href="https://support.yallo.ch/hc/en-gb/articles/360002401997-Why-do-I-have-to-cancel-by-phone-or-chat-" rel="nofollow noreferrer">here</a>).
Is this legal according to Swiss contract law?</p>
<p>Since I'm a layman I could only find <a href="https://www.fedlex.admin.ch/eli/cc/27/317_321_377/en#a404" rel="nofollow noreferrer">this article</a> which states that both parties have the right to terminate a contract at any time.
However, it does not specify the means by which the termination notice may be/must be transmitted.</p>

<p>Yes. The lawfulness of terminating a contract <a href="https://www.fedlex.admin.ch/eli/cc/27/317_321_377/de#art_1" rel="nofollow noreferrer">expressly or implicitly</a> (see &quot;<em>ausdrückliche oder stillschweigende</em>&quot;), with no further requirements, implies that outlining the specifics to that effect are within the parties' freedom of contract.</p>
<p><em>A priori</em>, the premise that &quot;<em>Yallo (telecommunication) does not accept written contract terminations</em>&quot; seems inaccurate. The site indicates that chat is a valid method for cancellation. Chats are in writing.</p>
<p>That being said, the matter --at least at the time of this writing-- sounds in misleading practices insofar as the chat functionality is unavailable. Clicking on the page for <a href="https://support.yallo.ch/hc/de/articles/360001085818-Abo-pausieren-oder-k%C3%BCndigen" rel="nofollow noreferrer">termination of services</a> issues the message that &quot;<em>because of CyberMonday the hotline is overstrained</em>&quot;. Similarly, clicking there on &quot;Chat&quot; leads to <a href="https://support.yallo.ch/hc/de/sections/360000244757" rel="nofollow noreferrer">another page</a>, so the customer ends up dealing with circular references rather than a chat. As such, the company is in violation of the <a href="https://fedlex.data.admin.ch/filestore/fedlex.data.admin.ch/eli/cc/1988/223_223_223/20210101/de/pdf-a/fedlex-data-admin-ch-eli-cc-1988-223_223_223-20210101-de-pdf-a.pdf" rel="nofollow noreferrer">Bundesgesetz gegen den unlauteren Wettbewerb</a>.</p>
