Text harassment

Hello. I have been texted by a certain BPO company (which I will not name for anonimity) everyday for the past few months and I mean EVERYDAY. They are asking me to come to their office for a job I didn't apply for. Sometimes, they even ask if I was on my way. They also said that I have a scheduled interview when I didn't even agree to come. I replied a few times and told them to stop texting me and take me off their message list since I already have a job but up to this day I'm still receiving their texts. Can I sue them for harassment because it has been really annoying and their texts are spam in nature.

hello. im working here abroad in the midfdle east. my problem is about my wife, who keeps on harassing me. it all started when she suspecting me of having an affair here at work. i dispelled the rumor and when i went home for a vacation last december, it was all thresh out. before i came back here , she even promised that she will stop harassing me. she even said that she believed me that i dont have an affair with anybody. and now she started harassing me again. what can i do?
