WHERE IS MY MONEY???!!!!!!

On the 9th of December i paid money into an incorrect Wolworths account. I called them the next day to get assistance. They asked me to submit proof of payment, which i did. I went to woolworths mall of the south and they assisted me with emailing the proof of payment again. I sent another email and they confirmed receipt. I then did not get any response and called them. The lady i spoke to, Zukiswa, on the 22nd of December said she traced the money and has submitted the request for the money to be returned to my woolworths credit card and this will take 4 business days. I sent another email after 4 days had passed and again, was told to wait for 4 days, which i did. I sent an email to missing payments and Shamieraa Van Der Vent told the money was refunded and will reflect on my statement. This was on the 6th of January. I asked her, how that is, because my balance is not showing any credit. She then responded on the 13th to say upon further investigation, she has found out that the funds were paid into an incorrect account (duh!, i've been saying this from the beginning) and that this was rectified and will be paid into my woolworths credit card. All the while i am calling them aswell, but their call centre people are unable to see anything regarding my conversations with this Shameera person. Lo and behold, today i access the woolworths app and i see an amount of R4374.56 DEBITED from my credit card AGAIN! i don't know why! now i have an owing balance and they would charge me interest on my daily balance, that i should not pay because this is their error. This amount was supposed to be credited into my account, not debited. where is the money? Now i am owed R8749.12!
