Vodafone Redbox Does Not Send Bills

I've been a Vodafone Redbox user, and for the past three months, my bill hasn't been delivered to my email. I had requested the bill to be sent to my email instead of paper to reduce waste, but for the last three months, it hasn't arrived. I've called customer service on 10 different dates, explained the situation, and they claimed to have opened a ticket, promising a follow-up, yet no ticket number or any details were provided. Getting through to Vodafone customer service is impossible, and I've had to put aside my work to deal with this issue. In my last conversation, a representative from Vodafone suggested I could retrieve my bill through the Vodafone Yanımda app. However, due to the rep's lack of knowledge, while the entry code comes to my phone, the second verification code sent to the Redbox modem line is unknown to them. When I mentioned this, they insisted the information comes to the phone in use. I am unable to access the Yanımda app. Vodafone Redbox is not sending the bill; they only share bill info via SMS, sending a link that shows an empty page for bill details. I've never seen such absurdity. I urgently request information on my latest bill being sent to my email and a resolution to prevent this issue in the future.
