The absolute worst ISP

The absolute worst ISP I have ever had the displeasure of working with. Their lack of communication has caused me so much inconvenience. My line was still occupied by the previous tenant’s ISP and I was told to call the FNO myself, which I cannot as I am not their client. After eventually begging for help from the FNO, I was informed of my situation. Immediately after that, Supersonic cancelled my order without my consent so I cancelled my service. Router has been shipped back of which I am awaiting an invoice. Now, my line is occupied by an order that was cancelled by Supersonic and I have tried countless times getting hold of them. I wait up to 30 minutes on the line to speak to an agent and their whatsapp service only replies after 5-6 hours. Poor poor service. Another thing you should consider is training your call centre agents better and telling them not to promise to get back to clients when they don’t bother. I have never had such awful customer care!
