Why am i paying for Things i don't Know

On 19/02/16 I checked my balance via online banking cause i wanted to make a deposit and realised that there 2 transactions I didn't do. Theres a reference of #PMT HONFEE 2 ITEMS ON 16/02/ and #PMT HONFEE 4 ITEMS ON 16/02/. I then tried calling the online help line which kept me on hold until i couldn't any longer. I then decided to use the app to try call them which kept hanging up and i couldn't get through to query it. I know it could be caused that my account was on negative, which why i was trying to make a deposit in the first place, but those transactions are there. So why am i paying an extra R300??. What is this #PMT HONFEE ??
