About this template
What is this template?
This is a formal letter of complaint for a consumer dispute involving a mobile phone contract. It contains a specific demand for a cashback credit and a time-limited warning of potential breach of contract action. It is not a court filing or a formal letter before action required by a specific pre-action protocol.
When should you use it?
Use this letter when a phone company fails to provide a cashback incentive after the contract has started and informal queries have failed. Use a formal Letter Before Claim if you have already sent this notice and are now ready to issue proceedings in a UK court.
What's inside
| Clause | Name | What it does |
|---|---|---|
| Mobile Phone Contract | Notice of Cashback Deal | Specifies the details of the cashback agreement and the date the mobile phone contract was originally entered. |
| To date you have not honoured the agreement | Breach of Agreement | Formally declares that the service provider has failed to provide the agreed cashback credit. |
| number of days | Deadline for Action | Establishes a fixed period for the provider to resolve the issue before the complainant considers further action. |
Who it's for
- a consumer whose mobile phone provider has failed to apply a promised credit or cashback deal to their account
- a customer seeking to establish a formal record of a contract breach before initiating a legal claim
- an individual notifying a provider of a deadline to rectify a missing financial incentive
