They ignore customers and only deliver half orders

The way the George branch does business is really unfair to customers. We’ve been buying from them for the past two years and have been very patient but this is now totally unacceptable. We ordered the combo 600l septic tanks in FEBRUARY already and about only a month later they delivered the tanks alone with no connectors. For over a month now we’re fighting for the rest of the delivery. Henk acknowledged the mistake and promised to deliver them then started ignoring us. I got through to a new manager who is also now ignoring us after explaining everything. This is unfair can we please have our connectors or a refund and you can come take your tanks. Think about us and not just yourselves for once please.
