Cell C not accepting a payment made 8 November 2021

When they start they say "Dear Valued Customer"---what does that mean for them? They even answered me via Hellopeter but no action. It has to do with my wife's account. We made a payment of her monthly account on 8 November as usual, sent proof of payment--but still when we received her new monthly account yesterday it still show as outstanding. My first review HERE was on the 6 Dec and they came back on the 7 Dec 2021 at 13:38 with the following "We sincerely apologies for the unpleasant experience. Kindly forward your proof of payment to *********x, so that we can allocate the payment" Now as you can see I had to react by sending the proof to *********----could not find such a email. However when you query something with Cell C they open a case no and send the number back to you as a reference-----on that page they state categorically give you the following email addresses ****** and ***----I have sent the proof of payment to all. On the 10 December 2021 at 08:31 I received an email from Solami Motha from ***--stating"Dear valued Customer, Thank you for contacting Cell C. Kindly be advised that you mat send proof of payment for the payment to be allocated on to the account. Please note, you may include the ID number, account code or cellphone number" I duly did that and I have sent the proof and all my wife's account detail to Solami per email 10 December 2021 at 16:54. After we received her account yesterday(with the amount still showing) I have sent a reminder to Solami this morning 7 January 2022 at 08:03--and to request her to advise what the problem is---I am now angry and discussed for the non performance of Cell C-----it should be an easy action to rectify the account. I want them to email me *** and send me a copy of my wife's account to indicate that everything has been paid up---note we have paid the current monthly amount (R342.99) received yesterday--also yesterday, so her account, as we speak, should be nil
