Unfair overcharge

Dear Simyo Customer Service,

I recently joined Simyo as a new client and was surprised to receive my first invoice showing a significant overconsumption charge. Unfortunately, I did not receive any prior warning notifications—neither at the 80% nor the 100% usage thresholds—by SMS or email, as I understand is standard policy.

At approximately 23:30, I received an email informing me that I had exceeded €100 in overconsumption. This was the first indication that something was wrong. By the time I logged in to investigate, the amount had already increased further, in large increments of €50 or more within a matter of moments.

I immediately paid the outstanding amount (€101) and turned off my SIM card to prevent any additional charges, as I am genuinely concerned about how rapidly the charges escalated and the absence of any warning system in place. Had I not been awake at that moment, the costs could have continued rising significantly without my knowledge.

As this is my first occurence with Simyo as a recent customer, and considering that I received no alerts regarding my usage, I kindly request that this matter be reviewed and a fair resolution offered - refund/ deduction of charges. This unexpected charge has placed considerable financial strain on me, and I hope we can come to an agreement that reflects both the unusual nature of this situation and good customer care.

I look forward to your prompt response and assistance. Otherwise, I will, regrettably, need to explore alternative service providers.

Sincerely,
Martavildan
