Shameful customer service

My husband and I had an account with MWEB for years without much of an issue, however, the most recent experience has terrible. We had the account when staying with my mother and cancelled when we recently moved. My mother decided to take an account in her name and had a conversation as well as emails with Lungisa Adonis who advised that instead of a new account, the old connection be transferred on to her name. This was over two weeks ago and although I tried to assist my mother to get assistance...nothing from Lungisa. We called time and again with no luck and last week got through to another gentleman (I have forgotten his name), his surname is Langeveld. He promised to speak to Lungisa and get us feedback asap and once again nothing. Very bad customer service.
