I have been sitting on the same mobile tariff for several years, which is considered archival today (you cannot connect to it, but you can use it). Due to the circumstances, my old tariff has many advantages over the new one - it is cheaper, minutes more, and you can still call all over the country as part of a minute package (intercity? I have not heard.) Apparently the operator for this reason and covered the bench, releasing a new line of tariffs, which are significantly more expensive, minutes there are less, you can only call in the region and the only thing that has changed for the better - it added a large internet package, but I don't need it.
It was an introduction, and now it is exactly what it was written for.
I regularly receive calls from the operator, where I am joyfully offered to switch to new rates and with great enthusiasm begin to dictate all the positive aspects of such a transition.
After listening carefully to them, I always ask the opposite question: "And what does my current rate not please you?", they are immediately lost and sadly - "Goodbye.." they put the phone =((
