Our Customer Complaints Code

Most complaints can be easily resolved through our complaints page. But if your complaint has taken more than eight weeks to resolve, or you’re looking for an alternative way to make your complaint, the following options are available:

Landline calls

Alternative Dispute Resolution (ADR)

If you’ve registered a complaint with us but it remains open after eight weeks, we’ll issue you with an Alternative Dispute Resolution (ADR) letter by either email or post. You can share this letter with Vodafone's ADR provider which is the Communication and Internet Services Adjudication Scheme (CISAS).. 

There are also instances where we would issue you with an ADR letter before eight weeks. You can expect an ADR letter if:

  • We’ve told you of the outcome of our investigation; and
  • The proposed outcome does not resolve your complaint to your satisfaction, and you have made us aware of this; and
  • We don’t intend to take additional steps to resolve the complaint, or offer a different outcome.

Once we’ve issued you with an ADR letter, you can refer your complaint to the Communication and Internet Services Adjudication Scheme (CISAS).

The service provided by the Communication and Internet Services Adjudication Scheme (CISAS) is independent, and free of charge. If you decide to contact them, they will first assess whether your complaint is within their remit. If it isn’t, or it is deemed malicious, it can be refused.

You can contact the Communication and Internet Services Adjudication Scheme (CISAS) on +44(0)20 75203814 (standard call charges apply), or online 


Written complaints can be sent to:
CISAS, Communications & Internet Services Adjudication Scheme, 70 Fleet Street, London EC4Y 1EU


Online Dispute Resolution

If you’re not happy with a product or service you bought online, you can submit your complaint through the EU online dispute resolution website.

It can be used for cross-border and domestic issues, although you can contact Vodafone's Alternative Dispute Resolution Provider directly for domestic disputes.
