Terrible service

I bought a 1 gig data on the 25th April using my banking app and I haven't received my data to date . The day I bought it I got an sms from TELKOM saying that there's a delay with the loading of my data and there was a ref number at the end of the sms . I called the customer care a number of times and every time I call firstly I'm on hold for 30 minutes before I get transferred to an agent it doesn't matter what time of the day you call . The first agent I spoke to said there's a technical problem with all the data that was bought via cellphome banking and their technicians were working on it . He asked for ref number and he immediately picked up that I bought 1 gig data then asked which bank I use then he said I must wait for 24 hours if I haven't received my data I must call of which I did and I spoke to Lerato who said she was going to escalate my problem and it would besolved asap but nothing happened on the 8th of May I called I think it was my 7 or 8 call and I spoke to Zethu who said there's no indication of data that I bought .I told her about the sms then she asked for the ref number of which she said it wasn't theirs I asked her how is that possible because I gave the ref number to a couple of people before and they were able to pick up that I bought data of 1 gig . Then she asked if my account was debited for the data that I bought i said yes then she asked for my bank statement of which I sent to her via email then she said someone will contact me regarding this matter and up to now no one has called me nor have I got my data from TELKOM.
