Our mission is to provide the best ISP service in the UK. We take pride in the reliability of our service provision and the maintenance of high quality customer support in every department.
However, occasionally our service may fall short of the high standards we set ourselves and if this happens we want to know so that we can continue to improve. We aim to resolve your complaint at each step of the process but, where this is not possible, you are able to escalate to the next level. You can raise a complaint by phone, e-mail or letter.
Step 1
In the first instance, we ask that you contact a member of staff in the department most relevant to your complaint:
- If your complaint is related to billing, you should contact our Billing team;
- If your complaint is related to technical support, you should contact the Technical Support team;
- If your complaint is more general, you should contact our Customer Services team.
Our Contact Us page lists the contact numbers for our customer facing departments.
An adviser will take all relevant information regarding your complaint, investigate thoroughly and, where possible, resolve the issue directly. If your complaint can't be dealt with by the team you initially contact, they will pass your complaint to the appropriate team.
Step 2
In most cases, no further action will be necessary. However, if we are unable to resolve your issue to your satisfaction, you can escalate your complaint to the department's team leader. If your complaint is made by phone, you will receive a call back within one hour. They will investigate further and report back to you within 24 hours.
Step 3
If you are not satisfied with the resolution or explanation provided you can escalate your complaint to the relevant department's manager who will respond within 8 working days.
Step 4
If you are not satisfied with the department manager's response you are able to escalate your complaint to the corresponding Operations Manager or Financial Controller who will respond within 10 working days of receipt.
Step 5
If your complaint remains unresolved, we will give you details to enable a complaint to be made to our Managing Director who will respond within 20 working days.
Alternative Dispute Resolution (ADR) process
If at any time during this process you are not satisfied with the progress of your complaint you can ask us to agree an early referral to our Alternative Dispute Resolution (ADR) process and we will issue you a “deadlock” letter. This will allow you to apply to CISAS (Communications and Internet Services Adjudication Scheme). CISAS is an independent arbitrator who will assess cases for consumers and small businesses and make a judgement so that the issue can be resolved. (We may decline to provide a deadlock letter if we do believe we will shortly resolve your complaint and are taking active steps to do so)
If your complaint is not settled within 8 weeks, you can take your complaint to CISAS without the need for a deadlock letter.
You will need to contact CISAS directly as we are unable to start this process for you:
