Lack of communication regarding refund

I requested a refund on 9th May 2021 of R 829 but after numerous emails no response was received.

I then decided to call Multichoice on Monday, 17th May 2021 just to be told by the consultant that her colleague made an error and as such my account was credited with the relevant amount instead of submitting a refund.

I was also told by the consultant the refund would take 24 hours meaning the funds would reflect in my account my Wednesday, 19th May 2021.

I find this type of service completely and utterly dissatisfying and unacceptable as Multichoice's agent made an error and now I as the loyal consumer need to wait who knows how long for money which is legally due to me.

Please investigate this matter with a matter of urgency otherwise I will be cancelling all services and moving to a competitor.
