I am a loyal subscriber to your service, you don't have to be doing me this dirty. May I please get my R399 refund

SADV service is poor, I am so disappointed. Your agents are ***********, they don't attend to clients on time. On the 2nd of November I paid for your services but I was rather charged an amount for installation, of which I didn't pay much attention to it, I only realized when my internet was not activated that something is wrong. To find out the following day vuma sent installation guys instead SADV activating my account. Now I had to write 100s of emails, WhatsApp texts of which I did not get rep****. This morning I paid again forthe services and today it went through but now the biggest issue starts when I was asking for a refund and finally one of your agents gave me a call and I did tell the her my situation but now she did not want to understand that I can not have a proof of payment that is not a screenshot because I had paid using my card number, instead of account. Proof of payment can only be generated when an account is sending to another account, card purchases don't get to have that feature of being able to download the proof of payment in pdf format. I gave everything to proof but she was not interested if I can not show the proof of payment in form of a Pdf. I gave her the OVR number, my router SR number and still she insisted. So basically SADV owes me R399 that only God knows when will I get it. Looking at reviews, I might even not get it back.

Not even one number can put you through to their offices, I had tried every number on the net, they all take me to other companies, if not going straight to voice mail. Honestly I want my refund ASAP.
