Dear O2 Complaints Team,
This email constitutes my final complaint regarding the handling of my account and the ongoing failure to resolve a serious service error.
Over three weeks ago, I formally requested a deadlock letter. To date, I have received no response and no explanation for this delay. This is a clear failure to follow O2’s own complaints procedure.
More concerning is the fact that one of my mobile numbers was disconnected in error. I was repeatedly assured that the number would be reconnected, yet this has not happened. These assurances were incorrect and misleading, and the situation remains unresolved.
I have:
Raised a formal complaint
Requested a deadlock letter
Contacted O2 multiple times
Provided all requested information
Attempted escalation via executive contact channels
Despite this, I have been met with silence, broken promises, and a complete lack of accountability.
This situation has caused significant inconvenience and distress. The incorrect disconnection of my number, combined with O2’s failure to engage meaningfully with my complaint, is unacceptable.
Immediate written confirmation of why my number was disconnected in error
A clear resolution to the issue, including reconnection or a full explanation if reconnection is not possible
Appropriate financial compensation for loss of service, inconvenience, and poor complaint handling
The immediate issue of a deadlock letter if this matter cannot be resolved without further delay
If I do not receive a substantive response within 7 days, I will escalate this matter to CISAS without further notice, including a claim for compensation and a full review of O2’s failure to follow its complaints process.
Please note that all correspondence, timelines, and evidence are being retained for escalation.
I expect this matter to be treated with the seriousness it warrants.
Yours faithfully,
