Harrasment!!

I received a call late 2013 from Viatek. He said he was calling to confirm delivery of cartridges which an ex staff member had ordered. A week later 3 cartridges were delivered with a R100 voucher & all ended well. They said just try the product they have the best cartridge even better that HP itself. Mar '14 I received the same call with the same story. He said it would be 5 this time, I thought it was strange as I thought this was a once off trail order, but I was told this was a bulk order which I wasn't told in the beginning. May '14 the same call comes in, he says it's the remainder of the order. He said it would be eight this time, when I queried why he said because of the initial order. He also said this would be the last of the stuff to be delivered. I spoke to them again late 2014 and was told my account is stopped and I'll have to call them if I then need more ink. This Jan 2015 I got another call for another \remainder"delivery which I now waited for Marius to call me. The ink was delivered and the inv. of R7800. Now when they called me I told them I'm returning their ink I was told they don't take back stock. I will be sending it back today...STOP CALLING ME!!!"""
