SPAMMER FROM HELL!!!

If you're not a customer yet, avoid MTN at all costs! This company will literally drive you crazy in its attempt to get more money from you. I chose not to upgrade my phone, and have been very clear that I am not interested in another contract, but for a year now have been spammed every single day ... I can get at least 10 calls a day, if not more. I have blocked hundreds of numbers from MTN sales and upgrades, but they just keep calling every day. I have emailed their complaints department ... no luck, it simply continues. Not only do they call me on my cellphone number, but they have now started calling me on my work line, constantly disrupting my working day. This is blatant harrassment.
