I will first emphasize that O2 is an absolute garbage internet provider.
I have an LTE connection with a subscription for 100 MB/s, Since I got it, the maximum MB/s that I recorded was around 40MB/s, and usually around 10MB/s or below.
This is extremely unacceptable and from further inquiry by phone with O2, this is way below their minimum promised speeds, meaning, they are in breach of contract.
I tried changing contracts, having called the English support line, they told me I can change to DSL or Cable for the price of 25 or 20 Euros per month, they told me on the phone they will call me back as they need to inquire about a further discount for me.
I never got that call back, after being ghosted for 4 days, I call O2 back on the English support line, only to be answered in German, the German person on the phone was kind enough to transfer me to the English line only for them to immediately hang up on me after hearing my problem.
After calling back, being answered in English, the person on the phone decided to abruptly transfer me to the German line, while I was mid sentence. After AGAIN, being transferred back to the English line, having to retell my problem for the third time, the person on the line puts me on hold for 10 minutes only to offer me a new contract for 49 Euros per month.
“This is the only option I can offer”, said the man, how can this be when I was already offered a lower price a few days prior?
He also said what I can do is cancel my current contract in order to get a discount on a new one, something the original person I called with never mentioned.
After I asked how to do this, he told me I should send A LETTER by PHYSICAL MAIL.
Why, you might ask, should I send a physical letter to a technology company instead of a simple email or online form?, the answer is, BECAUSE IT IS FASTER THAN EMAIL!!!
I already knew Germany is a backwards country, but I thought they already at the very least invented the telegram as form of communications, a person on horseback or a pigeon delivering my letter is absolutely not an acceptable form of communication.
This bring me to my main question. How can I prove that O2 is in breach of contract? Do I check my speeds every day and make a screenshot? Should I contact lawyers or can I simply cancel my SEPA direct authorization and let them contact me?
