Sequel to previous complaint against cell C

After a long struggle cell C finally gave me a new tablet of the same value and the case was closed. To my understanding I still pay for a new contract to access data on a monthly bases. This is after what I complained about aspects of their service mainly the tablet I sent to them and thereafter I discovered that it was broken. Initially they accused me of having broken the damaged screen before I handed it in at the branch in Key-west. All appears to have ended reasonably well except that I got a call yesterday which was claiming to be from lawyers who allege that I have to pay for months before I got the new tablet which means I should pay for the more than three months of not having my tablet - months during which I was accused of breaking the tablet, which I did not. After telling them that I have reasons to suspect that they are trying to **** me, they dropped the phone and the conversation ended. I hope they were not from Cell C otherwise I will be very disappointed and angry with cell C. I thank Hellopeter for assisting me!
