Does this Code of Practice apply to me?

We will let you know that we’ve received your letter within 48 hours of receipt and will provide you with a unique customer reference number.  Please remember to quote this reference number when communicating with us regarding your complaint.

Once we have received your complaint, it will be logged on our customer care system and investigated by a dedicated team.  We may need to contact you further as we look into the issue, so please ensure we have your correct contact details.

Once we have reviewed your complaint, we will let you know the outcome.  If you have contacted us by phone, we may be able to resolve the issue on the same day.  If we have been unable to resolve the complaint by the end of 5 working days, the matter will be escalated within Avanti and we will keep you informed of our progress.

In the event that you remain unsatisfied with how we have handled the matter or if we have been unable to resolve your complaint within 8 weeks, you may refer the matter to independent adjudication by following the Alternative Dispute Resolution Procedure described below.

Compensation or Refunds

Avanti always endeavours to ensure you receive a fair deal.  Refunds are considered on an individual basis taking account of the nature of your complaint; whether you have been disadvantaged by Avanti’s actions; or where the service you received has fallen seriously short of what is normally acceptable.

Avanti does ask that customers use their service in accordance with the Acceptable Use Policy. 

We would encourage you to also follow the fault reporting routine set out in your welcome pack.

Alternative Dispute Resolution Procedure

If your complaint has not been resolved within 8 weeks of receipt, you may refer the issue to the independent Alternative Dispute Resolution service provided by Ombudsman Services Communications.  Provided that the complaint is within their remit, they will investigate it free of charge.
