Poor service

I am trying to get DSTV to link my account back to my e-mail address for the past two weeks. Because of a hearing imparement I found it difficult to communicate via telephone and DSTV was informed about this as well as the fact that I said I prefer e-mail communication, my account is still not linked back to my e-mail address and absolute no communication was received from DSTV. When it came to payment of monthly subscription they are very quick to send you a reminder via wattsup but when it service is required from their side, nothing happened.
