Standard Bank motor finance and Holland insurance is busy doing ***** on customers accounts!!!!!

Standard Bank just add a Holland policy to our Motor Vehicle account ,while we have insurance with Iwyze. .They have no permission to do that ,and now they ignore our emails to payback our money that they deduct for Holland insurance ..If you go to the branch for help ,they take you to a phone and thats worse ,because the person on the other side is *********** to assist. ..The had no right to just add a Hollard policy while we have iwyze. .It's such a struggle to get hold of them to pay back the 3 instalments they already deduct ..,It's a shame Standard Bank !!! No help from them😢
