How can I stop repeat text messages?

[AC Question]

I have an LG Optimus F7 and for ab out the past year I've started to receive repeats of received text messages from different numbers, I haven't been able to pinpoint if it is a software issue (don't have hangouts or antivirus app), or if it is a carrier issue because I know only the carrier for 2 out of the 4 or 5 persons that it happens with. It gets very annoying because I can get up to 25 repeats and it can last for up to 4 days... I am about to go to the store and replace my phone!
