Bad customer service

On the 31/12/2025 Telkom SA debited more than my monthly sub in my bank account and later claim that my account was overdue. Even on 29/11/2025 they added money on top of my sub and later was amended after I phoned the call centre, yesterday Telkom shop in key west mall in krugerdorp demanded my bank statement from November to December to check that money was there before the debit order went off, and money was there in my account and I was told to go and pay my sub at pep store cause of I've reversed the money that was debit on the 31/12/2025 cause I got a policy which should debit also, and now today morning my mobile router is blocked from getting service, even when I phone the call centre my sim is blocked, Telkom SA services are very very bad its a month to month thing, they don't have a due date on debits and later say the debit order was unsuccessful even when there's money in my account, and from years back my monthly sub was from the last day of the month and the last was the 1st of each to make a payment, now they're debit orders goes off when ever it feels like, they're service is very poor, bad am unhappy on how I've been treated by this business they're unreliable and today I can't even get hold of customer service I am restricted.
