Absolutely terrible service

I am most upset with the service i received. I made an eft payment on 9 april 2020 and sent the POP in. However the payment did not reflect on my statements for May and June . I enquired and was told over and over that it was showing. Then i received an email with my statement...i was told to check it. The statement wasnt mine. The money was allocated to another person with the same initial and surnam3 as me. I was told it was my error however how did payemnt go to the person with the same initials as me. Not to mention,i have made payment like this before and NEVER had a problem so how is it suddlenly some error on my part. I am emailing non stop with no help. J keep getng told they are short staffed but how long does this take to recify. Afterall, ive only been waiting 2 months already!!!! How much more patient must i be. I received my new statment and guess what, the money IS STILL NOT REFLECTING
