Pathetic and Poor customer service! ******* and *****!

On November 2nd. I sent and email to *** with an advise of an agent that doesn't have a name (they never give their names) from whatsapp. This CSA said that I paid into the wrong account and therefore I need to request for refund from that email attaching my proof of payment and my account details for refund and I did that. I was hopeful that I would get my refund on time because I even received an response with a reference number SA216262 on the very same date. The account number I paid to was on the payment instructions on my invoice I paid to it with and immediate eft fee because I did not have my easy pay number and I needed my line to be opened. When I queried again on whatsapp I spoke to a someone again with no name who advised I needed to make payments to my easy pay number which they sent via email and I paid the second time and my line got opened. I am still waiting for my refund and everyday I ask if there's anyone who is attending to my query since the second after getting the reference no one got back to me. I was even blocked on whatsapp for asking for my money, SADV is a **** company their are not loyal and they are not committed to their customers. I am a customer service agent and I definitely know what is customer service. If I don't get any joy from them today I am taking my query to the ombudsman as well and if it means that SADV pay me for the airtime I am borrowing from people I will sue them to pay me to my last cent as I am a customer that have rights.
