For over three months I've been trying to resolve the problem that my phone can not connect to the towers (no data or text available) twelve different times I have called the customer service spending on average 2.5 hours each time and talk to up to five people each time because they escalated the case to a supposedly higher technical people.
At the end of the long wait and repeatedly turn off the phone, check the settings, reset the this and that, look for such network parameters they hang up while waiting for the last step that finally will solve the problem. Then I had to start all over again or they tell me that they will call back and when I answered they hang up. IT IS A SCAM.
You can hear on the background the chickens and dogs barking when I call.
Finally, I end up getting another service provider because I was fed up with the lack of response.
