If you're having difficulty paying a bill, don't ignore it.
Talk to your phone provider as soon as possible. They might be able to help.
Your provider is not obliged to offer you any of these things, but if you explain your situation they may be willing to look at options with you.
For advice on debt and managing money, the Citizens Advice consumer service might be able to help.
You might also want to contact National Debtline or StepChange Debt Charity. If you're not able to make any of your repayments or if you're facing the threat of court action, seek free, independent debt advice straight away.
Avoid having your service disconnected. Some providers charge reconnection fees, which must be paid on top of the debt owed.
Disconnected customers might also be treated as new customers and have to go through credit-checks and pay deposits.
If a bill is unpaid, firms usually contact the customer.
If you do not pay, your provider might restrict your account. This could mean outgoing calls are restricted to emergency calls and calls to the provider only, while inbound calls are unaffected. You might be disconnected if payments continue to be missed.
Some telecoms firms have rules for certain groups of consumers, for example those who are vulnerable. They will make extra effort to contact these customers before restricting or disconnecting their service.
If you don't agree with the charges on your bill, check that no one else in your household has been using your phone to cause these charges.
If nobody recognises them, contact your service provider. It might be helpful to send them a copy of your bill, highlighting the charges and the reasons why you think they are incorrect.
If your provider doesn't agree, you can follow their formal complaints procedure. Details of this should be available on their website or from customer services.
If you remain unhappy, or if your complaint has been ongoing for more than eight weeks, speak to an ADR provider about an Alternative Dispute Resolution (ADR) scheme.
The ADR provider will look at your arguments, and your provider's, and come to a decision they think is fair.
There are two ADR schemes, Communications and Internet Services Adjudication Scheme (CISAS) and Ombudsman Services: Communications, and all service providers must belong to one of these schemes. Your phone company will tell you which scheme it belongs to, or you can use our ADR checker.
If you are referred to a debt collection agency while in dispute with your provider, contact the agency and explain this to them.
Communications firms have a right to chase money they believe is owed to them. However, we would expect them to allow you time to resolve your dispute. It's also important you follow your phone company's complaints procedure.
If you feel that you have been mistreated or harassed, either by a telecoms company or by a debt collection agency, complain about the way you've been treated.
Write to the telecoms company or debt collection agency explaining your complaint.
You can also complain to the debt collection agency trade association, the Credit Services Association, if the company is a member.
If you have a dispute about a billing or contract issue, you can seek advice from the Citizens Advice consumer service.
If you need advice about debt collection and dealing with your debts, you can find sources of free debt advice through the Money Advice Service. You can find further information on what to do about mobile phone debt from National Debtline.
