Our website and e-mails have been off for 1 week now!

We have had domains registered with Afrihost for several years now and every year there is a problem when renewing. We have renewed and paid our domains on 23 April but when you try to visit our website it shows as expired. I have logged several support requests but every request gets answered by some stupid line on how it is not their problem and then it gets deleted. Afrihost is costing our company money!!! BAD service and definitely not a company I would recommend to any business! They cost your business money!
