Data not loaded and bad service

On 25 April 2018 I bought 5gig data via my banking app which was not loaded for some reason .I received an sms that it would loaded shortly which did not happen . I escalated the query to Telkom ( Irene branch) who requested my bank statement so they submit the documents on my behalf . I received no feedback until 20 May when I received a call to resubmit my bank statement which I did . I kept following up with no joy as I was always asked to resubmit my bank statement which i did right until 24 May 2018 . On 31 May I got a call confirming receipt f my documents and assuring me that the data would be loaded in 72 hours . Ever since I have been following up and no one can give me an answer on why the data is not loaded, instead al I get is promised that team leaders will call me and does not materialize .
