SPAM VOICE TELEMARKETING FROM MTN

I am gatvol of this company and their automated spam telemarketing messages. Getting them throughout the day and even had 1 on Wednesday night after 10pm!!!

Phoned their useless directory to try and speak to some1. A lady that works for them said sorry and she also gets them amd they do not know how to address this issue in the call centre. Emailed their complaints email but they have not even responded on that. What do you need to do more after you have removed your tel nr from the marketing database???
