Phone number given to someone else before 3 month window of no use.

<p>I lost my phone and it took me a little over a month to get a new one, and when I went to MTN to do a sim swap I was informed that my number has been given to someone else because "it has no been used for 3 months", and so I cannot have my number back. This is *******. I used my phone during early to middle of July and thus My number should not have been given to anyone else. I demand it back. I want this resolved asap.</p>
