Rotten service consistently

The worst possible service given consistently. I cannot understand how and business can make the same errors every month giving you the same rotten service. Every month my line gets cut - my billing is incorrrct - I pay my account through eft - fir the past 24 months - every month I call in requesting billing via email - never ever get my statements - lines are cut without warning - I have my dad 82 years old - who requires access to telephone services due to his illness - but all Telkom tell me that there system automatically cuts services and cannot activate manually. I wish South Africa had an alternative land line supplier - Telkom is a grudge purchase - who can but only one thing correctly and that is to get everything wrong - rotten service consistently
