Protecting Your Privacy

At Mainstream we collect and store a lot of information about our customers, for example who you are, where you live, what services you use and who is responsible for paying the bill. We will use elements of this data to confirm that we are speaking to the right person when we receive a call to further protect your information.

Should You Have a Complaint About Our Service

Our aim is to resolve the problem to your complete satisfaction and our Customer Services team will try to do this as quickly as possible, preferably during your phone call. If this is not possible we will agree a course of action with you and respond as quickly as we can. Billing queries can take a little longer to resolve as we may need to investigate the call records in further detail. If you are not happy with the way your complaint has been handled, please call and ask to speak to the manager of the Customer Service team. The contact number is Freephone 0800 169 6000.
