TERRIBLE CUSTOMER SERVICE

I paid my account R9100 on the 06 May 2020, I paid using a link they sent via Sms with my details which is suppose to be an Instant Eft, I called Customer service today the 7 May 2020 spoke to Simnikiwe and Andiswa Botha who both couldn't confirm my payment, I was advised to send a POP to *** and I did so, I sent my bank statement and the receipt number I received on the link yesterday after making payment. what ****en irritates me is no one seems to be accountable for finance..thus is a useless shop, I also sent my Poo to *** no one came back to me. Please check my money as I did an INSTATNT EFT WITH DETAILS GIVEN BY YOUR COMAPANY AND ..OR ELSE REFUND MY ****EN MONEY AND STOP SENDING ME STUPID MAILS THAT I OWE U WHILE I PAID OFF MY ACCOUNT.
