Vodacom Collections Department - BAD (in service) and *********** (in dealing with customers and queries)

I paid my Vodacom Subscriber account via the Vodapay App. This app allowed me to access to Vodacom profile and show my account balance due. So on 31 January 2022 @ 22h28, I used the app to pay my cellphone subscriber bill of R1183.90 (Reference number: ***). The vodapay app processed it successfully and I could print or screen shot a proof payment. Shockingly when I woke up on 01 February 2022, I received a message from Vodacom Collections reminding me that my account is in arrears. I called the collections department 15 times (for the week between 01 Feb and 4 Feb 2022) and when I connected to a consultant (all female), they deliberately cut me off. Today (08 Feb 2022) I called again to do a follow-up and after calling the collections department 5 times, again whenever I connected with the 5 female consultants, again they deliberately cut me off when they saw my profile. After calling for the 6th time a colored male assisted me and he was super helpful. To my detriment, after 9 days since I paid Vodacom, my account still reflects that I'm in arrears, and the service request that was logged (Reference: A2-T435-8GOXA) never received any attention as it was still pending. So my credit profile is in a mess because of Vodacom and their *********** back office. This was the second time that used the app to pay the same bill. The first time I used it was on 01 December 2021 @10h45 for R804.00 (reference number: ***) this payment went through successfully and my Vodacom account was up to date the same day. I would like to alert future users not to use the VodaPay App, as it's useless and will lead to a lot of frustrations. I suggest that people rather use their banks to pay accounts or bills. In terms of my arrears account, I'm disgusted with the POOR and *********** service delivery from VODACOM COLLECTIONS DEPARTMENT. HOW ON EARTH CAN MY PAYMENT (WITH ALL EVIDENCE SENT - PROOF OF PAYMENT AND MY BANK STATEMENT SHOWING THAT THE AMOUNT R1183.90 WENT OFF MY BANK ACCOUNT) NOT REFLECT OR BE PROCESSED - AFTER 9 DAYS?
