Shocking service from M-Web

I am a M-Web customer, I contacted M-Web to assist with moving our fibre service to our new address on the 30 August. I have been sent from pillar to post. Three weeks have now pasted and I still do not have fibre service I am paying for. I have made multiple calls, sent multiple e-mails and still nothing. Today I phoned M-Web and requested to speak to a manager and was told that managers in M-Web do not take calls from customers. This is shocking service!
