Disgusting service and no refund

I hate having to come on a social platform to express my anger and disappointment in a company. But what is a person to do when you logged a complain in store and being told by a telkom staff member that if im unhappy about something then i should go to hello peter. So what happen is,I payed more then i should have to cancel a contract. And when i got a invoice the next month i saw that i was owed money. I went to your telkom store in mall of the south and the lady there said she would request it to be payed back into my account. That was like over R1000 so i couldnt just leave it. Weeks went by and i went back to the store asking when will i get my money,she just said her system showed that the money was refunded. Of which i asked where because my bank statement showed nothing,i even gave the copy of my bank statement to proof it. As i went there numerous times with no luck of getting my money back i got annoyed and told her this is not funny anymore that i have to come spend my whole lunch hour here with no feedback. I even asked her,does she not check up on her quiries unless i came there? Of which i got a very rude responds of im not the only quiry she has. And if i feel unhappy i should logg a complain on hello peter. I was so shock to that responds that i just left. Calling the call centre is another waste of time and energy as i was holding for over an hour to be assisted. Please can i just get my refund back. I promise myself i would NEVER buy a product or recommend anyone taking anything from telkom with such bad service.
