Amarex Service

Is there a Courier company actually seeing their customers as valuable? I have had lots of successful shipments with Aramex before, but now all my parcels are late. I run an online business and advertise on my website that parcels would be delivered 1-2 days. My account with Aramex is based on next day delivery. We dispatched a parcel 1 DEC for delivery 2DEC. On 4 DEC the client advised they have still not received their goods and needed it that evening. After calling Aramex at 11h00, I heard back from them after 15h00 saying my client can collect or it would only be delivered on Monday... How can I expect a client that paid courier to go and collect her parcel, this because they misplaced her parcel? I am now in a situation where I need to refund this client. Till now I am waiting for the JHB branch to get back to me as promised on Friday regarding this delivery. I am moving my account. Surely the R10k+ I spend with them monthly is not worth it for them.
