Regret porting to telkom

<p>I ported to telkom mobile few months ago. In my written contract I have stated that my account must be debited on the 15th of each month. Telkom have been making deductions on my account on the 25th of each month. Payment did not go through on that date (25th) and was rejected. So rejection fees were charged. Telkom has suspended my account. I do not deny lowering the said amount. I should not be charged that rejection fee as telkom was at fault by being in contravention of my contract ie for deductions to go off on 15th not 25th. I have phoned customer care and visited the branch but to no avail. When I visited the branch I told them I Will make payment on 15 April. I am paying for telkoms mistake ie wrong deduction dates by my account being suspended. I have never been faced with this before. Did I make a mistake porting to telkom ....?</p>
