ROTO TANK...DISGUSTING

Ordered 6 tanks from Roto Tank. The sales lady Yolande said I can pay before I collect and no need for payme t or deposit. I asked my client to pay me 50 % so I can secure the tanks and they do. I place an official order and then Yolande said I must pay in full before they will manufacture. When I ask to speak to a manager, Yolande tells me they dont have a manager. Rather go to JOJO tanks...much friendlier and cheaper too. Roto tank appears to have no business ethic and quite disgusting service. The order value is only R65K but i guess they dont want business.
