Non-existent aftersales service

I bought an Epson printer at the end of November last year. The printer has been sent in for repairs 4 times now. And I, as the customer has to drive all the way from Pretoria to Johannesburg to book it in myself. I'm done taking this printer in for repairs, I'd like for Tarsus to take it back and credit our account. I was informed by my account manager that they no longer sell Epson products so I have to contact Prima Toys with my query. Prima Toys is not my supplier, I didn't buy this printer from them and it's also not MY problem if Tarsus can't get a credit note from THEIR former supplier. You guys are quick to take our money but your after sales services is non-existent.
