Fido spamming me?

Anyone else with fido getting bumbarded with messages the last 3 days? They have sent me 6 messages in the last 3 days. I have already blocked them since their messages are annoying (I'm on the family plan so all I need to do is send my portion to my dad when it's due) they have never messaged this much and it's getting extremely annoying as my phone still shows when a blocked number tries to message me, I can't see what the messages say since I have them blocked but I'd like this to stop now because they send some of their messages at 5 in the morning and at this point sending multiple messages a day is getting annoying. Why are they spamming me like this? I have never received more then one message every once in a while, they have sent multiple the last 3 days and it needs to stop.
