In Dec my account was credited from my previous contract to this upgraded one of 378rd and my normal installation is 810 so the did not Debit me in Dec putting me in a minus for 436rd what i then did was increase my installment to 1000 instead of 810 to cover for the minus now after paying 1000 for jan Feb March and April am being told am owing a 1000 rand again and my account was suspended this telkom like doing always i feel this ********** if there is not good explanation and is very unfair t
