Unhappy

I’m not happy at all with Telkom. I took a contract with them years back, last year the contract ended and turned into a month to month basis. I went to Telkom to cancel it completely, just after I cancelled it the same day they deactivated my SIM card for why I don’t know. They deducted money from my account from account for which they said I owed the last month but my thing why did you deactivate my SIM card with data on it, till today I’m waiting for that answer. I’ve been calling with my airtime and I hold long to get help and if I do the phone gets dropped. Till this day Telkom is deducting money from my account for what I don’t know
