Step 1: Formalise internally

Note dates, reference numbers, staff names, and promises. Email the complaint inbox summarising facts, desired remedy, and deadlines. Attach speed tests, photos of kit LEDs, and copies of contracts. Escalate through tier-2 technical teams before anything else if the issue is purely synch speed.

Step 2: Regulatory hooks

Automatic compensation on certain missed appointments and delayed repairs applies to major providers signed up—verify eligibility. Ofcom does not resolve individual fights but tracks trends; cite relevant General Conditions if mis-selling occurred.

Step 3: ADR

Choose the scheme your provider lists (CISAS or Ombudsman Services: Communications). Present a concise chronology; ADR is free to consumers. Include evidence packs zipped—clarity wins.

Avoid: Withholding direct debit without advice—missed payments hurt credit files even if you dispute service quality.

When switching helps

If infrastructure limits mean problems will never be fixed on copper, migrating technology beats endless complaints—SwitcherMate shows realistic upgrade paths at your property.

CISAS versus Ombudsman Services

Your Final Response Letter should name the correct scheme. Deadlines matter—ADR screens tend to reject bundles missing mandatory eight-week timelines unless deadlock letters exist. Organise evidence chronologically with bold dates; adjudicators read hundreds of cases weekly.

Even during disputes, pay uncontested portions of bills if advised—partial non-payment complicates goodwill.
