Worldline

To whom it may concern if you really do care, I have been with worldline internet, since 2013, and in 2016 I believe I was offered a promotional bundle of phone and internet at a speed of 25mbps down and 10mbps up I never got up to 5mbps up until august 2021 after pleading with tech support to increase my speed as the upload speed of 3mbps I was getting for donkey years wasn't sufficient even though 10mbps was advertised. Around august 24th 2020 I noticed I couldn't make calls with my said home phone which I barely even use, my calls were strictly with usa/canada as indicated when I first got the service, I could never make calls outside this zone, unless I subscribed for long distance calling as I was told, I always get this voice prompt telling me that long distance calls is not permitted, this lack of outgoing calls even to zones that was allowed lingered to the next day 25th aug, so I contacted support they offered to look into it and kept me on hold eventually he said that he couldnt make outgoing calls via my account in their server and I was told that he was going to escalate the problem, since its above his knowledge, on the 26th of aug I was told the problem was resolved. On the 28th of aug I got a bill for my phone I have never received a separate bill for for 4 yrs on the phone plan since its included in the bundle, on this bill it has over 400mins of international call made to moldova to 2 different numbers, my first guess was a hack has occurred internally inside worldline because long distance calling was not permitted in my plan even if I tried, but to my surprise after speaking with customer service explaining this to them, they claimed its possible to call long distance, which is quite new to my ears and this was not the case when I first got the plan, however I remember when I couldn't make outbound calls tech support confirmed something was wrong internally, I believe from experience in cybersecurity, that a hack took place, and my sip credentials were stolen configured elsewhere, when I further looked into the bill, I noticed that the calls were made from 1am on the 23rd of august to 8am on the same day racking up over 400mins, I have relied on international calling cards, for my long distance calls and its served me well, I have never made calls outside the allowed zone on the worldline phone, I don't understand why they cant see that something was off and needs to be looked into, when I looked into my routers logs I noticed a couple of hack and login attempts but only ip address from my local network was successful since my sip credentials is not visible to me and worldline claimed that the default password is secure and denied user the rights to change it to a stronger password, I believe this was a hack and worldline is aware of this mysterious bill they are trying to shove down my throat, worldline kindly check your records I barely make calls with that phone why all of a sudden will I feel the need to use it through out the night when am suppose to be resting as I am studying and working. Where is the time? I have included the bill and modem logs so you all can see and secondly pull up the call recording on the 24th of aug 2021 and listen to it. My bill have remained the same for years until this problem arose I was lucky to have discovered it on time, its up to you to find how they did it and patch it.
