No Email Communication available , inconsistent billing

<p>I have noticed the growing trend of no direct email communication available for customers in many companies. One has to either phone or fill in an on-line form so no record on the customers side of the communication. The customer receives billing etc via email however it is always a Noreply email & there is no other way to reply , email directly. This in my opinion must be a strategy by big business & it is very customer unfriendly / unfair / frustrating.</p> <p>PS: Telkoms billing is inconsistent & nonsensical , charging widely different charges from month to month for the same line item. Beware</p> <p> </p>
