MTN making my life difficult

<p>My phone got ****** last week. I phoned MTN to block my number. I got told it got deactivated because I have made no calls from it!!! But I still use this phone to get OTPs</p> <p> </p> <p>Now I can't get into my gmail, I used to access this on my phone, I cannot access gmail on another device without entering an OTP that gets sent to my number.</p> <p> </p> <p>All my OTP's and personal calls come to my number. Your call centre is useless and cannot assist, and most of the time after putting my number in it says "Thanks for calling, goodbye" What is that about? You really know how to alienate your customers.</p> <p> </p> <p>I e-mailed your customer care. i get an automated response saying someone will respond, and guess what! No-one responds!!</p> <p> </p> <p>It is urgent that I get my number back before it gets recycled. I was still getting OTPs on my number 2 weeks ago. Can someone please sort this out!!!</p>
