Poor service rendered

So I went to AVBOB on the 2/05/2018 to cancel my policies, I had a savings education plan policy with them, submitted all the documents and I was promised that my money will be deposited in to my account in 2 weeks time. On the 9/05/2018 I recieved a payment for the first policy however the 2nd one was deposited in to someone else's account that I don't even. I called Nomonde on the 18/05/2018 to find out when am I gonna get the 2nd payment, she told me that it has already been deposited and I told her that I did not recieved it, she then gave me a number of the department that processes the funds and spoke to Julie , thats when I found out that my money was deposited in to someone else's account. Julie promised me a call back on the very same day however she did not bother to call back, I ended up calling back for feedback and she transferred me to Abner who was responsible for processing funds. He apologised for the inconvenience and he promised that by Monday my money will be in my bank account and he will personally call me to give me feedback, guess what I'm still waiting for his call and I still haven't received my money back. I'm so disappointed by the service that I was given by AVBOB and I don't think I'll ever recommend it to anyone.
