MTN is not hounoring their COVID-19 online application

I have a problem with MTN debit orders that I keep reversing them. I app**** for the contract package comprising wifi router and a SIM Card from online application, but during courier delivery only to find that the delivery guy had SIM Card only, there was no router. The delivery guy gave me papers to sign before he could give me the package, then he gave the delivery package later. Then I asked him why the delivery is so lighter, I expected something heavier than that. But he said he had no clue what package should be delivered. Then I opened the box and checked what is inside the box, and found that there was only SIM card inside, there was no wifi router.

Then I rejected the delivery. I told the delivery guy that I cannot accept that SIM Card because it was supposed to go along with the wifi router.

Then I went back online to make call back. One of the agent called back, then I explained the problem with the package, he said he does not know how to help me with that. Then I made another call back, then another agent could not help me too.

Then I left things as they are, until the email communication started from MTN care centre. Then I rep**** them that I don't have contract with them because I did accept the delivery, but they have not rep**** me. MTN kept on debiting my account, and I kept on reversing those debit orders.

Today as I speak, I got call from MTN, from gentleman by a particular gentleman using this number +***6, and asked me what is happening with my contract, and I explained him that I don't have a contract with MTN because I app**** online for the package of SIM Card plus wifi router, then I was delivered with only SIM Card, hence rejected the delivery. Then the gentleman advised me that I should go to MTN shop, then I stopped him right there. I told him that I app**** online, and expected delivery from courier as promised, but the delivered package was wrong. Then I asked him why would I go to MTN shop to resolve online application issues ? Then he said then I should go to police station to make and affidavit to avoid the MNT to take me to Credit Bureau. Then I said no, I am not going to police station to do such an affidavit. I don't understand why they did not follow up with courier.
