Statement required from Telkom showing all payments - why is it so difficult?

I opened 2 contracts with Yelkom in August. I have not received statements, instead they’re debuting my account with amounts higher than the contractual amount - despite them confirming the contracts are both capped. I’ve requested explanation for the amounts devoted, no answer. In the meantime they KEEP processing debit orders against my account for money I don’t have and they’re ruining my credit record. The customer service is not helpful - they said their manager will call back, that was more than 24 hours ago. Incompetence at branch level is one thing, but having to wait weeks for a reconciled statement from head office is unacceptable. Telkom what are you doing?
