Supersonic bad service

Their call centre Agents sucks I've called them 10 times today in need of help for them to unlock my router because a simple thing by changing the address from one place to another. To request assist you have to call more than 10 times that all your airtine gets finished and when you request the agents to call you back they don't,I spoke to this Agent by the name of Natasha I asked her to call me back because I was holding for long and my R80 airtime was almost finish but she didn't which is unprofessional.I hope you don't do business nor buy anything from them trust me it's easy when they sell something for you wait until you have to call them asking them to activate it,you'll spend another R100 to R150 of airtime trying to get them to assist you,wow I'm fed up they must just come take their router.
