A Very BAD service from Mondo/MTN

I was sold a Sim-card subscription from this company about a few months ago, i informed them that they need to deduct their money on the last day of each month. the first month, no debit order went through and i thought maybe i was being given a grace period. second month, third month went by without collecting any debit order.

I then tried to call them to inform them of the debit order that they need to Run from my account without any success. I am now realizing that they have listed me as a bad payer on my credit score rating and this is affecting me very badly, though i am not looking for any credit currently.

They are the one that initially called and tried to convince me in buying their product but now i have been trying to contact them without any success.

I tried using the Sim card that was provided but the service has been suspended.

I am now being affected by the service that I'm not even enjoying from this company and believe they prey on people thinking they are not knowledgeable on these products. they are selling lies to people.
