Poor service from Vodacom Fibre

For the last two and a half months I have been unable to send e mails although I can receive them . I have called the help line on more occassions than I care to remember, and have follwed their suggestions as to how to correct the problem. Nothing has helped although occassionally one or two emails can be sent after this intervention. There have been NUMEROUS service requests placed , most of which one has no response to , or as in the case of the last one I was told they rang my home number but got no responce so they closed the SR. !!! May I suggest that is why we give the company our cell phone details!!! After working through the trouble shooting exercise with the consultants many have suggested the modum may be faulty. Due to a total lack of response to resolve the problem I am now at my wits end. I have attempted to get the problem corrected, have spent a fortune on call fees, have paid for a service I do not receive so now have decided it is time to cut ties with a large company that does not believe in customer service. It is not the route I would have chosen to go as we have used Vodacom fibre for over two years but the total lack of interest is just so frustrating.
