Bad agent experience- Sisipho Ngcumza

Very very bad experience, my mom opened an education plan for her grand children with an agent by the name of Sisipho Ngcumza in June, they agreed to start the premium on the 1st of July and to deducted in the 1st of every month, however they deducted in June, she called the agent back and complained and she assured her it was an error and that it won't happen again, in July they deducted in the 1st, but now in August they go again and deduct on the 25th, she just called Sisipho back and she was rude as ever, she claimed there's nothing she can do about it and that my mom can go and reverse the money from her bank and cancel the contract if she wants too. Clearly all this Sisipho cared about was getting her commission and doesn't care what happens afterwards, because even if mom would ask her questions she'd claim it's not her fault and another department, and when she asks to be transferred to that specific department she'll claim she doesn't know how too. Everytime she'd ask a question, Sisipho would say she doesn't know the answer.. This is by far the worse treatment by Old mutual, and to say her investments are with Old mutual... Please investigate the issue is in regards to your education plan because with other investments and policies with your company there is no problem we experiencing except for your education plan, unless your agent doesnt know what she's doing before I cancel my contract
