Disgusting client service

Firstly, I am extremely disappointed in the service I have been receiving, I actually want to take my business elsewhere. I gave you guys a call on Friday last week at around 9am and was promised a call back within 30 minutes, I am STILL waiting for that call back. We have had endless problems with our wifi for the past week, my partner has lost thousands of rand of business because of this and I feel like it's taken as a joke! We moved and are paying MORE than what we were for the same line, I don't know why I'm having to pay more, yet I'm struggling 10 times worse now than when I was paying less. I want to know why I am having so many issues with connectivity, I feel like I'm paying a ton of money for nothing!! Then, Monday night I contact your whatsapp number where someone asked me what my issue was, I rep**** immediately and STILL no response!! It's disgusting!!
