Mweb Technical Support bad service

Mweb Technical ***. On 30th April, at 15:07, I hung up after 11 minutes wait. On 3rd May, at 12:55, my call was answered after 7 minutes. The call centre agent said he could hear me, but then cut me off in seconds! They know who you are because you have to capture your details & get a pin to verify it is you on their answering system. He could easily call back. The automated system repeatedly tells you that the agents are busy! Can't the system tell you what position you are in the queue? And how do we know the agent's are actually working and callers are just hanging up?
