Adjusting my home loan installment

I sent an enquire to your general enquiries line, [Email Removed] on the 18th, but still no response. <br> <br> In total I've paid R24600 EXTRA into my flexi home loan account, over a period of a year. This month I withdrew R7750 and then R5900 (2 weeks apart). On both occasions I've received a notification from the bank stating that my home loan installment is going to go up (as if I've app**** for a bigger home loan and have to pay them interest for a bigger loan??). This is not the case, this is MY money that i withdrew and you cannot charge me interest on extra money that i paid?? And if that is the case, then why did you not lower my installment every time I paid extra money into my home loan?? I've also not once received a home loan statement from Absa, even though I've stipulated this on my online account. <br> <br> I'm seriously considering moving all (vehicle finance, home loans, credit card, platinum accounts) to another bank because it seems Absa just have the habit of not responding to client's emails or enquiries. <br> <br> I want answers urgently please!!
