unhappy customer

i have been a loyal customer to Telkom for more than 5 years but recently they are showing me flames they are ready to ruined my credit score

first case they debited money before the right date which leads the account to bounce back and i was told i must pay interest of R202

second case they refuse to change my debit order date to month end as i was service notice to my previous work and the only pay date was month end by law

thirdly i was hacked on my bank so i decided to switch my salary to a different bank i called them to give them my new banking details they refuse to change it they said it was be active for 3 month and i cant make manual payment on the 25th it must be 10 days before. i told them i will only have money on payday but to them they said i must go borrow money to make payment

Telkom is the only service providers that have abused me emotionally while paying them. I am very unhappy with their service and it looks like they don't care.one agent told me apparently Telkom is business if they don't get money i will be liable for interest

i have noticed they really don't care they cant even listen to customers need. i just want to cancel this contract ASAP

Kind regards Hleketa Gaveni ***
