Refund and then charged

I reached a resolution to my complaint on the 20th November 2019 with Wendy and Tebogo to refund the following: - Refund for the R300 incorrectly transferred - R150 airtime - R150 recall fee Total R600 was refunded.

Then on the evening of the 20th November around 6pm the recall fee of R150 was charged. The recall fee should not have been charged and been voided. I called the call centre again and the team leader Kholi dropped the call in my ear! How do you reach a resolution then go back to square one AGAIN!!! THIS IS FRUSTRATING and I want my R150 to be refunded to me. I want Tebogo to resolve this immediately!!
