Purchased data but was not credited according to the purchase made

I recharged my airtime on the 28.02.2019 with R70 to be able to buy myself the promotional “mo’nice” data 8gig(10days) for R74. I had airtime prior to recharging with R70. So I purchased the 8gig data which was not credited into my account so I gave it 24hours to reflect still nothing. On Friday 01.03.2019 I logged a call with Telkom I was given ********** 0 as my reference no, on Wednesday 06.03.2019 I called and still my query was noy resolved at around 14h20 I received an sms saying my query has been resolved so I call the toll free number “180” to find out how has it been resolved only to be told that I can not be refunded my airtime nor get the 8gig data I purchased which was not loaded because the R74 airtime that was used to purchase was actually refunded the same day. But I did not get an sms saying your R74 and has been returned that same day I purchased the data. I was aware that I was using out of data rate from my free bonus airtime that I receive every time I recharge. I kept checking my bonus airtime balance every hour that day but there was no other airtime in my account. This is a very bad service I got from Telkom, until today I have not purchased any data as I fear the same thing will happen. I am still looking for a network that has better network coverage and data bundles that I can move to. I still want my airtime or data that Telkom de*****ed me. I need the statment of my cell phone number for that day 28.02.2019 showing when was this airtime refunded before taking this up with relevant legal parties.
