****** / lost Funds

I Made a payment of R1000 into my account, I have requested time and time again fir Mobicred to update my account since I have deposited money to them and I have sent them the POP over and over directly from my bank however every single time the response is " we acknowledge the email and have escalated it to the relevant department., its been two months now and instead they keep telling me that my account is in arreas for R765 now. They refuse to engage with me, they don't want to acknowledge or update my account and cI have expressed that I will not pay more money into my account until they acknowledge and update the R1000. My bank confirmed to me that the funds are indeed with Mobicred . I am completely frustrated and dissapointed, Up until 2 months ago I had such a good experience with Mobicred however I refuse to let my R1000 not be fixed and updated, its too much money and it is in their account.
