Slik Consumables is a ****

This people called me sometime last year and begging me to buy toners from them, by then I didn't know who they are so I just ordered 1 toner and the sales lady begged me to order 2 toners instead which I eventually did order those 2 toners and the told me that I'll only pay them after 30days but after 2 weeks they called me non stop demanding their payment which I processed. Now they sent another 4 toners which I didn't order saying it's part of the first order and now they demand that I pay them and I called them the day I got that parcel and their receptionist said the manager will call me which never happened until now that they demand to be paid
