Payment allocations - *********** call consultants!!!!!

My name is Zeenat. I have been a cell c customer for the last 6 years and I am extremely displeased with the service I have been receiving for the last 2 months. My existing contracts are due for upgrades and I am unable to upgrade because the system shows I have an outstanding amount of R910,14 since May 2019. Mond you I have a debit on my account. I have never missed any payments. While I understand that the payment may have "gotten lost" but nobody ever called to let me know. After countless call to cell c customer service I make a cash deposit of R920 and attach the given reference number of *** which I received from the consultant as that is the outstanding account number. I send the proof of payment and request for the payment allocation to be made to that account. My current account number is ***. Today 25 Jan I received an sms to remind me to pay R220 on the 27th Jan 2024. Mind you my debit date is 27th of each month. So I call the customer care and speak to a lady called Kholo. She tells me the R220 is my amount for 27th because the payment of R920 was made to the incorrect account. How difficult can it be to attach the outstanding payment to the correct account. The logs it again and the new case number is ***. I am so frustrated that people are hired to to the job and are so ***********. I just need th payment to reflect on the correct account so that I may upgrade. Please assist in this regard.
