I cancelled contract 2 months ago and the contract has lapsed and would have gone over to monthly contract if same was not renewed. I reversed same and cancelled the debit order and paid fees on same just to realize the debit order went off again double this month. Why Standard bank are you nit honoring the client's request and why did I have to pay fees if you are anyway not reversing them ad stopping the debit order as instructed. Now this is *****ing!
