Worst Internet service provider in South Africa

I am a supersonic customer since last year and use to struggle with the poor service and internet connection.I recently needed to move house and I called the supersonic team and informed them on the 7th June 2021 that I will be moving. As the new area that I moved is not with fiber I was told that I have to change to LTE which I did and made my order for the 28th June 2021 to be delivered to my new address and they will just add the amount of R999 to my existing account for the new device. To my surprise nothing came to my new address on the 28th June 2021 I then made the first of several inquiries just to find out I needed to pay a upfront R999. For the device to be delivered and not as the agent have said previously I made the payment the same day that was on the 29th June 2021. And send the proof of payment to the collection department. On Friday the 2nd of July 2021 I called and ask to why I have still not received the new device or sim card.I explained to the gentleman that I work for a funeral policy company and my main duty is to launch claims for our clients so that they can get their payouts to buried their love ones and If I don't have my internet I can not provide my clients with any service or payouts.The agent went on and canceled my order. And added that I am not interested in the product. This I only found out on Tuesday when I called again to inquire about my device and sim. I asked to please speak with a manager and was told that Bonga will call me back I am still waiting for that call. I asked what is the managers Surname and was told we are not allowed to know that and that the agent Refilwe will not be assisting me anymore and put the phone down.It is now the 7th July 2021 NO INTERNET and no device.I was told that a case will be opend and they will look into it I went out today and had to buy a Rain sim card just to be able to work as I have failed to provied my clients with the service and Dignity to buried their love ones. As till now I still have no vlear answer tk what will supersonic be doing ti rectify their mistake and lack of service.I still have no answer to when will they be delivering my already paid for device.The service rating from me will be a zero star and I will not ever recommend this internet providers ever to anyone.I have explained to all my clients due to the fact My service providers Supersonic lack of service and not taking any responsibility I will not be able to help them for now
