Incorrect Deposit

I mistakenly, while doing internet banking, deposited money into the Telkom account that I had previously paid on behalf of someone else. I mistakenly hit the incorrect beneficiary. I called Telkom the next day and spoke to a lady by the name of Nohlanhla Hlope who had told me I would receive a reply and some feedback in 72 Hours. 5 days later i then call in and get through to a man by the name of Sboniso Nkosi who then emails the previously lady. Fast forward a day still no feedback from either. After a lot of calling in I eventually get through to Mr. Nkosi whom can not help me but escalates the matter to his manager whom is still dealing with last weeks complaints and tells me that i will be contacted before 1pm today.

Luckily i had emailed my proof of payment through to both Miss. Hlope and Mr. Nkosi and yet neither has responded. I have sent 4 follow up mails to Miss. Hlope and have still received no response. The service Telkom gives is truly shocking and I shall never in my life take out a contract with them or make the mistake of ever recommending them to anyone else.

Can anyone assist me.
