very unhappy supplier

Signarama Pretoria ordered stock from me that their customer urgently needed. I sent items from Durban and CPT to fulfil their order to their customer. I never got paid. They also held onto my stock for almost two months and then i had to pay the couriers to collect the goods again and send back to their rightful locations. All at my own expense, just to secure my stock? When i tried to escalate it to head office they said that it was a franchise and so not much they could do.

Anyway, to this day, after invoicing them for the courier, they continue to ignore my emails and it is safe to say that i wont get refunded. This has cost me time, effort, money and huge frustration. Crazy and so unprofessional. Avoid doing business with them, especially supplying hardware to them without payment and especially with the praetoria branch with Francois. Thanks
