Bad customer service with Smart Shopper

I had a problem with not being credited with Smart Shopper points when filling up at BP. I wanted to e-mail the documentary proof to Pick n Pay, so on 25th November I went on to their website to find the necessary e-mail address. Under contacts they do not give an e-mail address only a telephone number. After phoning ********** 288 a number of times and pushing the correct numbers given to me by the "computer" for Smart Shopper, I was never able to speak to a human. I therefore sent a comment via the website (it does not allow attachments) asking for an e-mail address. They rep**** on 26th November saying management will contact me. I heard nothing. I sent another message via the website early on the morning of the 29th November asking someone to contact me. I have had no response, not even an acknowledgement this time. All I am looking for is an e-mail address so I can forward my documentary proof. It is their system that was at fault but I am getting nowhere. It is not a vast amount of money, but rather principle. Terrible customer service.
