The steps to resolving your complaint
1
Our aim is to take no longer than three weeks to deal with even the most complicated of complaints. The resolution of your complaint might include actions to put our mistake right, an apology, an explanation or compensation.
2
If you’re not satisfied that we’ve sorted it out, or you’re not happy with how we’ve dealt with things, we’ll carry out an internal review of your case. We’ll look into how we’ve handled it and the resolution offered.Â
3
We will let you know what the outcome of the review is and the reasons for our decision.  If we agree to carry out other actions following the review we will let you know how long it is likely to take.
