I didn't sign up to this service

I would like to register a complaint with you. I visited one of your stores to question my billing and was very surprised to note that I am being charged for a service that I have no knowledge of.

In October 2021, you started to bill me for the below :

TELEMÓVEL

 CONSUMOS                      01 mar a 31 mar

Comunicações Móveis Nacionais 5 Conteúdos - Digitais especiais – Subscrição

Total Telemóvel 9,951

I am told it is a subscription to some sort of cooking service. I am also told that it is something I had actively subscribed to.

ANACOM have informed me of your responsibilities for record keeping : Cabe ao operador provar que autorizou expressamente a realização do pagamento de bens ou serviços prestados por terceiros (outra empresa), devendo guardar a declaração de consentimento durante a vigência do contrato e do prazo de prescrição do procedimento contraordenacional (3 anos para micro ou pequena empresa ou 5 anos para média ou grande empresa).

I fully dispute this signing up process and I would ask that you provide the proof of the sign up without delay.
