Motorola KRZR K1m

Its a decent phone however I am seeming to have a problem with the inbox for text messages. For some strange reason it only will hold 6 messages and then if someone sends one and i have 6 already in the inbox i will not receive the message until i have cleared all the messages. The frist day it ocul hold 40 so i dont know why all a sudden it can only hold 6 and it doesnt give me a warning that the memory is full because there is tons of memory left on the card. I brought it in to the store i purchused it from and explained the problem they reset it and claimed it was fixed however it still has the same problem.. Ive called rogers and they said they have never heard of it and sent me on a wild goose chase htrough mnay lines,holds and computer...
