Can someone reply please!!!

I have emailed Telkom on a few occasions to advise I have moved and that I need my landline transfered or moved, however it has been 3 months and still no reply. <br> <br> Based on that I would like to cancel my landline. Whats the point in paying for no service. I would also like to be refunded for having to pay all these months with no landline owing to no one getting back to me.<br> <br> How on earth can a telecommunications company not communicate, come on!<br> <br> Highly annoyed customer!
