3 attempts to get through to call CENTRE

I had a problem with my mailbox not receiving any mail( turns out I have exceeded my 250mb cap. I did not even know that existed but I suppose over 5 years it could get full) I tried to contact them and was put on hold for 8 miniuts then someone answers and when I tell them the problem tells me to hold and disconnects me. Second attempt waited also about 8-10 mins then someone picks up and immediately puts down. Third attempt I get through after another 8-10 mins and get told that my mailbox is full and I will have to individually go through my entire mailbox and delete the mail I don't want. Can't delete a bunch of mails as there is no space I have to delete individuals until there is more space to delete them in bigger batches. I certainly never knew all this I thought my mail was on my computer not their server, I asked to speak to someone senior to see if they could help. Yes I was told and put on hold and hung up on! On their Facebook page when I told my story I was told that there is nothing they can do as I am one of their smaller packages! ( yep I only pay about R1000 per month) and they have done the best they can. Afrihost thanks for your condescending attitude.
