Mweb - very poor service

Think twice before dealing with Mweb. I have a contract with them and to communicate with them is a nightmare. It is so easy to get a new contract as one of the contact numbers is the sales department. If you try to cancel or alter your existing package it is impossible. In their contact details there is no number for cancellations. You have to go through the sales department and they then transfer you to the retention department and then nothing happens. I have tried a few times over the last month to try and get in touch with the retention department with no joy. They do not even deserve one star.
