Irritating sms messages

<p>Receiving sms's from MBD indicating that they are trying to get hold of me and requesting that I contact them. Received a final notice via sms. Never received prior notices so I would like to know way I will receive a final notice. I have now phoned them 20 times and only 2 was the number actually answered. The first time I was transferred and got cut off. The second time I gave my number and they would have phoned me back. Got cut off again. I still do not know why the hell they are trying to get hold of me but their sms's is irritating the hell out of me. The best of course is the sms saying that they are trying to get hold of me. Not once did I receive a phone call from them. Either answer your phones, actually phone me or leave me alone because it is an irritation...ref on sms: ********** ********** 37.</p>
