Telkom useless company

Telkom is the worst company to work through this is the third month with a billing problems because they are a useless company first i needed to change banking details then i was told it will take a month to change and that i must do an eft i do the eft then they debit my account after that i had to reverse the debit order they then proceeded to charge me R 200 for a bounced debit order which i disputed and then the following month they didnt bother to debit my account until i did a self service payement and then they sent me an invoice for two months, then this month my pay day is today they attemted to debit my account yesterday when i was not paid and all i was told today is it stipulates in the contract that they do not debit over a weekend wonder when this came into play as we supposedly should know this, then they are now causing my bank to charge me R100 for this unsuccesful debit and their R 200 for unsuccessful debit absolute *******s this company is a waste of time money and effort.
