Bad service from MTN via Mobile Plus

<p>So I decided to get a phone through MTN/Mobile Plus. When I received the phone only to find out after a couple days that the speaker is faulty. I informed the supplier and they promised to arrange for the courier to come and collect the phone. After several calls to them reminding them about the collection till today nothing has happened and I'm stuck with a phone that I can't use. I knew that they would debit my account today and to my assumption I was right. I told them I want to cancel this contract because I received then phone on the 26 of April and informed them about the fault on the 2nd of May and nothing has been done about it.</p>
