Extremely bad service. Will be looking to move to another ISP soon

Had a WiFi issue which was reported to Supersonic 8 days ago. Have had to follow up with them daily sometimes twice a day to get the same response which didn't really provide me with an understanding of the cause of the technical issue and progress to resolve it. The various call centre agents were clueless in responding to most of my questions. At some stage I requested to speak to the supervisor or someone senior who might have an understanding of the process to no avail. I was instead told that the issue had been escalated to Vumatel and they were waiting for a response. While the agents were polite and apologetic at no stage did anyone from Supersonic follow up with me to give me an update or try to manage my expectations. I was even referred to Vumatel as if I am their client, which was a gross underestimation of my needs as a client. Supersonic needs to up their understanding of what business they are in and improve training of staff to understand, follow up and provide feedback as expected. I would rate them a zero if such a rating existed. In the meantime, while vumatel has finally attended to the issue, it remains unresolved as they also cite capacity issues. Again I'm concerned about the lack of insight in pairing technicians who work overtime without sufficient support back in other streams that requires further action once the technician is on site. We have a long way to go in business if we have companies who have no insight of their customer requirements and negative impact this causes to them.
