Advertised campaign not upheld

In early March I responded to an adverti*****t (copy attached) from Pick & Pay and purchased an Epson L3150 printer on 4 March 2020 (copy of receipt attached).

In terms of this deal I was to receive one ream of printer paper for 24 months. During my visit to P&P, Greenstone (Edenvale) during April & May I experienced problems getting the paper as this was, apparently, never loaded onto my Smart shopper card which was used during the purchase of the printer.

On 18 May, during a visit to the above-mentioned store, a lady at Customer Care phoned the Smart Shopper Card division but none of the three different persons she spoke to, apparently, knew how to rectify the problem because, without fail, the call was cut-off as soon as they realised that they did not know what to do.

Is there anybody, within Pick & Pay, who can rectify this problem OR am I expected, for the next 21 months, to go back to the same store and every time produce evidence of this transaction to the manager on duty to enable him to approve the purchase at nil cost?

When this matter was reported, P&P acknowledged receipt and allocated a unique reference number, 400189, to this matter but my question as to when the matter would be resolved was NEVER answered.
