Don't bother with Supersonic

I recently moved and needed wifi in my home. Metrofibre has monopoly on the infrastructure in my building and so I looked for an ISP that can help me get it done. None of them have month-to-month options on fibre, except MTN that has an AirFibre option for a little less in cost per month. I signed up at the Mall of Africa MTN store, with a lady named Khanyi. She wasn't extremely knowledgeable on the product because like she said, it is very new and I was their store's first customer, but she was very helpful and very friendly. During the process of placing the order, Khanyi advised that payment will only be due after installation, before the service can be activated. While in the store, I logged into my account via a link that was sent to complete the setting up, the website expressly said that I can either pay now or pay later but the service won't be activated without payment. She also said that I should be getting communication for installation either by Tuesday or Wednesday. After signing up on Sunday, I received a series of emails and it was there that I saw that MTN offers this service, but it is Supersonic that deals with all the techical. Supersonic WhatsApp'd me yesterday saying that my order is not complete because I need to make payment. Based on the information relayed to me by Khanyi and as well as the information on the Supersonic website, I dismissed the message.

Checking on the progress of the order today, I see that it hasn't moved. I private messaged MTN and Supersonic on Facebook, both of which took exceptionally long to get back to me. MTN comes back to me while I'm having a chat with Martha from Supersonic. MTN says that I need to contact Supersonic. Martha says that my order won't be completed until I make payment. I sent her a screenshot of where the Supersonic website says "To activate your service, an upfront payment is required. You can either do the upfront payment now, or later, however your service will not be activated until payment is made." This clearly says that service activation will not take place until payment is made, it does NOT say anything about the order not being fulfilled and no installation until payment is made. Martha insists that my order won't move forward without payment. I ask payment for what when there's no antenna, no router, no nothing in my house that would even allow me access to this service that I need to pay for??? Essentially I'm expected to make payment for placing an order. Martha refuses to acknowledge what their website says and even sent me a response that was meant for another customer. Very unprofessional and extremely misleading information on their website, versus what their agents are trained to say when questioned. It's safe to say that Supersonic will not be getting my business. If they're so full of lies this early, I don't want to imagine the stress I'll have to deal with after they receive my money. I will tell everyone I know not to do business with Supersonic.
