Texting problem | Koodo Mobile | Forum

Hello people, I haven't read all the topics here but I was too lazy to read them all.
I have a problem with my Koodo Motorola W385 phone. I have it since my 15th birthday which is in October and have had no problems with it until now.

Since this morning, I have had replies on my phone like "Message cannot be send, Check Message status" whenever I texted someone, and that's like EVERY TEXT I SENT and it would say General Problems on the message status. But the people I txt would reply back, like they had the txt? I'm confused; What does that mean? How can I fix it? and I've seen the Koodo CS pretty much sucks, they don't even have a FAQ. :(

Any help here? It's getting on my nerves,
