Upgraded LTE to Double Data promo and did not receive the double data

On 18 November 2017 I went to Tygervalley mall's Telkom shop, upgraded my LTE Data to the 100GB daytime + 100GB night data (DOUBLE DATA PROMO) so I was advised that I will receive 200GB + 200GB. The consultant said I will get pro-rata data and the full new amount data from the 1st, so 1 December I viewed my available data online at the Telkom self service, and it said I only have 100 GB + 100 GB and not the 200 GB + 200 GB as I was advised. I travelled to Gauteng and went into the Mall at reds Telkom shop on Sunday the 3rd of December to find out what is going on, the consultant advised that she cannot see anything and there was no upgrade made and that I can not AT ALL do an upgrade. I am really unhappy about this service I received. I believe that there was an error made and should be fixed remotely urgently as I cannot go into a telkom shop back and forth and nobody has an answer for me.
