Always avoid ringing if you can. The most effective complaints are made in writing as if you need to escalate an issue; there is already a trail of evidence. However if you do need to make that call:
1. Don’t press any options at all.
2. Dial zero, multiple zeros or multiple hashtags.
3. Choose the option for ‘thinking of leaving us.’
4. Provide nonsensical voice recognition answers such as ‘courgette’ or tea cosy.’
5. Say no to every question.
6. Make a note of the order of options so you can quick fire through them should you have to ring again.
7. Source lesser-known numbers via websites such as https://www.saynoto0870.com or find a customer service forum for the company in question on social media where others might share alternate numbers.
8. Make smart calls: ring at optimum times and call off peak if you can.
9. If you do get through ask if there is a free direct number for future calls.
10. Don’t waste your breath or their time and yours. Escalate any issue sooner rather than later!
