No Service

I have struggled to get a reply from Afrihost since 08/05/ regarding my new bill I received for May. I have sent 5 emails already, received 1 pre-writen email from the CEO with detail where I can send my query, which I have already done. When I phone I get a message that their lines are very busy and that I must send a mail. I tried to get assistance on the online chat, but they cannot help either because it is an accounts query. Have been with them for almost 2 years, and this is the second time I receive bad service, but the first was not this bad. I am disgusted. I pay for a service as well, and not just the product.
