Please cancel my contract ASAP! It is unbearable!

Hello!

I am writing to formally cancel my O2 contract effectively immediately. I have already sent multiple emails, submitted contact form and talked to your team several times via O2 hotline.

I submitted an online cancellation request, but the cancellation date provided by your system is 12/01/2027, which is not acceptable. 

The reason for my cancellation is that I have consistently experienced poor network performance despite having an “Unlimited Max” plan (upto 300 Mbps). Specifically:
- Significant speed drops and throttling during normal usage.
- Inconsistent download/upload speeds, often far below the advertised maximum (eg, speeds sometimes as low as 1–10 Mbps).
- Unreliable connection when using the SIM for mobile internet or hotspot purposes. 

-Download speeds have never exceeded 30 Mbps, far below the advertised maximum.

- I have attached documentation of my speed tests, conducted over both Wi-Fi and mobile data, as proof of the persistent underperformance.

I am unable to livestream, attend Zoom meetings for work, or use multiple devices simultaneously due to slow and unstable connection. 

These issues have made it impossible for me to use the service as intended, particularly for work, streaming, and daily internet needs. 

Additionally, I have purchased two new routers (tp-link), thinking the issues might be related to my old O2 HomeSpot router, which is approximately 5 years old, yet the problems persist. This clearly shows the problem is with the O2 service itself.

I only signed the new contract on December 1st, 2025, just 5 days ago, after experiencing the same issues for months (since September) with my previous O2 Unlimited Smart 15 Mbps plan. I upgraded hoping the “Unlimited Max” plan would resolve these problems, but the performance remains unacceptable. I request written confirmation of my contract cancellation, with the official end date not later than December 31, 2025.

I am an O2 customer since 2020 with two contracts! Now I cannot take this anymore. I only want to keep my original contract.

Thank you for your understanding!
