ILL treatment of customer service

I'm disgusted in the way capitec is treating it's clients, I have submitting my frustrations with this company and nothing gets resolved, this morning I spoke with a lady called Wendy from complaints department and she promised to get back to me with feedback, thus far she has not acceded to her promise. Over and above I have tried to call a team leader by name of Takalanis but as usual, no answer.

My complaint is that I had a loan contract with capitec and, my loan expired in March 2018, however the system showed that it ends on April 2018 and I've quiried this. This makes problematic for my credit score because my name is not cleared with capitec. This in essence means that capitec overcharged me but this Wendy character do want to understand that, this is so annoying and I need this to be resolved as soon as as possible because I will not allow no money to be deducted from, My account further more.
