Telkom stole my Money from my account

My December invoice was R3008.20 and was overdue therefore services was suspended. I made a payment to Telkom via the Online service of the full amount on the 19th of January 2019. Since then my service has not been restored as yet. On the 30th of January 2019 a debit order of R2500.00 went off on my account which is impossible as I could not use my phone during January 2019 due to suspension and therefore I should only have paid the normal R890.00. Telkom has ****** money from my account even after making contact with them on the 23rd of January 2019 and they promised to fix the problem.
