SIM card delivery very slow

I ordered a replacement SIM card with data on 11/5/2015 - order number AFR221262. I was informed after a few days by the courier company that they would deliver on Friday...not too bad but a little slow and outside Afrihost's quoted 48 hour turnaround. Nothing arrived on Friday so I phoned the couriers on Monday 18th to query. Oh no the delivery date was actually Friday the 22nd! 11 days to deliver a SIM card. One for which I have already been billed and for which I am being charged PRO RATA from the 11th. I am appalled that this can take so long. Rather pop it in the post. I managed to get the couriers to agree to deliver on Wed 20th, but I still find this unacceptably long. Afrihost's response was apologetic but said they could not do anything once the courier company took control. Well they can perhaps use a courier that is a little more speedy.
