Horrible horrible horrible billing policies

I was sent a bill for R1558 which I had to pay by the 15th, I have had medical challenges keeping me from getting to a pay point but managed to pay R500 on my bill by the 15th! Telkom still disconnected my line and and said I had to pay an additional R1300 to have my line reconnected! Its ****************! I am well within my R1500 credit limit. I offered to pay them the rest on the 23rd but noooo....I am fed up
