Giving away your personal information to some stranger

If I can give this company - 200 stars I would.

I have a prepaid number with this excuse of a company that I've been using over 3 years now for WhatsApp and social media.. This morning when I wanted to use my WhatsApp the number is no longer registered.. Phoned Mtn and they just politely said oh sorry we gave away your number. Because you never use airtime on it. Absolutely ridiculous...I use wifi no need for airtime...

They juat said sorry they can't do anything about it. The poor guy that bought this number said to me he is getting all my OTP and get messages from my contact on my WhatsApp because it's now his number and everyone think it's his number. So hopefully I don't get ****med or some sort of ***** will happen now... Absolutely disgusted with this
