Mweb utter disgusting customer service.

I have a 10 Meg Fibre account with Mweb and I'm only getting 1Mbps throughput. My account is suppose to be uncapped and unthrottled. I also need to update my contact details with Mweb and have been trying to get hold of them all day without success. I tried to send a email to them but get a message that their support mailbox is over it's quota. The service from Mweb is shocking to say the least. I WILL definitely cancel my account with them and move to a fibre provider that can at least render a service and which you're able to get hold of. What utter disgrace Mweb customer service is. I guess I can't complain about the service as it seems that customer service doesn't exist.
