UNSATISFACTORY AND APPALLING UNPROVIDED SERVICE!!!!

TELKOM decided to debit short and thereafter I paid by EFT the outstanding balance; they decided to debit me again resulting in an over payment. I had put in a request for a refund of the EFT payment made in December 2019 first by their online app, which didn't work as the logged request was not found when i first called to follow up; which resulted in that call being the actual initiation of my request for a refund. I was informed of the turn around time of resolving my query. I check my e-mails to find that i was e-mailed from a no reply e-mail that my case is closed i wait for a few days to receive the payment notification but nothing. TILL DATE I HAVE STILL NOT RECEIVED ANY REFUND AFTER CALLING, BEING SENT FROM PILLAR TO POST AND PROVIDING ALL THE NECESSARY DOCUMENTATION REQUESTED. IT'S UNFAIR AND THE WORST SERVICE I HAVE RECEIVED, NOT FORGETTING THEIR BOTHERSOME NETWORK.
