I bought a router with them for the first time, in Nov 2023, paid upfront, pro rata. I didn’t pay at the start of Dec, they stopped the connection, 4th Dec, I called to cancel, this Indian lady started crying for no reason and being theatrical, she said she had scheduled the cancellation (which was the first lie) I’m still getting sms’ about an outstanding balance for “Dec” mind you, we are in Dec, so how do I owe you for Dec when I’ve cancelled and your services were stopped by you and the month hasn’t ended, they’re billing innocent people for months without an internet connection , hoping you’ll just pay to let it go. They’re the most mediocre company I’ve dealt with in South Africa, especially the Sandton call center, they’re the worst. The Cape Town one is helpful, the ladies Akhona and Nolitha are very helpful.
