HORRIBLE INTERNET SERVICE EXPERINCE

I would like to share the horrible service experience meted out to me by SADV in the provision of the internet service. I cancelled my contract with them after several pleas with them to correct their internet connection which was intermittent and sometimes no connection at all. The contract was cancelled on the advise from VUMA office to do so and get SADV to release the line before I can re-apply to get a new internet service provider. In trying to avoid SADV on the 17th Oct 2024 I went to MTN Wonderpark to re-apply for VUMA fibre internet connection. I was then send a payment link which does not the show the name of the service provider. To my surprise after making the payment I received a "Thank you for payment" message from the same SADV which I had indicated to VUMA that I do not want them. Due to all of this bad experiences I requested the R399.00 refund from SADV but they refuse to refund me, and therefore wondering if they are trying to enforce their internet service on me which gave me such bad experiences???
