I have found this thread from 4 years ago, and it actually related to me so much. Unfortunately, the case was closed even without the problem being solved. Just as always!!!!
It's pretty absurd that this is the best customer care O2 has to offer.
I have been patient the previous 6 months where my internet has been on and off almost 6 times a day. It became unbearable so I called customer care, and they did exactly as mentioned by the two people. Some people do not speak English (it's funny I was working in telecoms in my country and English was a requirement, because even when you look at Munich, it's not only having German speaking people), the people arrogantly hang up the phone, especially after that log waiting time to get through ti someone to help you, which is a waste of time and money in airtime. The technician makes appointments, takes half day of your time and doesn't turn up. O2 Pleaaasssseee this is becoming unbearable. Close the company or give up back our money in refund as we pay full amounts for services that are not provided.
Ofcourse I am out of words to ask how my internet problem is going to be solved, hence running to the, mobile internet(from another competitive company), and here we are, I find other people with the same problems, and the same terrible customer care from the answers below.
Customers are not stupid. They're not going to come out of nowhere and complain about a problem that doesnt exist. Please!!!
