#Unhappy customer

I purchased a refill cartridge toner from the kiosk in Cape Gate, the sales person was very helpful and also told me there was a 6 month guarantee. When I inserted the cartridge and tried to print, just blank pages. I immediately dialed the number on my receipt, no reply, went on to their website got an alternative cell no when dialing, subscriber not available, I tried the 071 number on the receipt again, no reply, dialed about 5 times still no reply. Called the alternative 081,subscriber not available. So I wanted to know what to do next, I called a different ink cartridge company and then tried to open the toner myself. Unintentionally everything came apart. Called Inkfill again, Salesman said I should bring it in. Went back to the kiosk, salesman called the owner, and said their technicians must have a look at it but only on Monday 1st March, I spent R399 and all the owner said was that she could not sell it to another customer because it was broken now, If I had received an answer when I called I would not have opened it. My question is are we in this day and age not concerned about customer retention and delivering excellent customer service or just concerned about the bottom line. We'll, learnt my lesson, it could be that indeed it was faulty but we will never know, will we? because of the error on my part.
