Urgent: Disputed High Data Charges (€300+) – Notification System Failure

Dear Simyo Customer Service Team,

I am writing to formally contest a recent invoice totaling approximately €300 due to unexpected mobile data overconsumption. I have been a loyal Simyo customer for over two years, and I am deeply distressed by this situation.

The charges occurred because my home Wi-Fi disconnected while I was using my phone. I was completely unaware that my device had switched to mobile data until it was too late. Most importantly, I did not receive any warning notifications—neither at the 80% nor the 100% usage thresholds—via SMS or email, which is the standard policy I rely on to manage my costs.

I am currently unemployed, and a bill of this magnitude is a financial impossibility for me.
Given my two-year history of timely payments and the fact that Simyo’s automated warning system failed to alert me before the bill reached this extreme level, I kindly request:

A significant reduction or waiver of the overconsumption charges.
The immediate unblocking of my phone number so I can continue my job search.

I value Simyo’s service, but as a long-term customer, I find this lack of protection against bill shock unacceptable. I hope we can reach a fair resolution. If this cannot be resolved, I will be forced to look for a different provider that can offer better usage safeguards.

I look forward to your prompt assistance in resolving this matter.

Phone no: 06XXXXXX

Sincerely,
Akshay YADAV
