Terrible service

I live in cape Town and my online order ended up in Joburg! After numerous calls and emails, I received a msg from a lady saying that she received my goods, which means her order has gone to someone else! How long will it take for Edgars/courier company to sort this mess out? I'll be closing my account with Edgar's which I've had for almost 20 yrs. The service at the call centre is pathetic with no one really knowing what to say or understanding my queries.
