Refund for Migration

Mtn migrated my Home Internet Contract automatically on the 26th February, before the 24 months could expire and I was charged a migration fee for this. I strongly believe it was unjust that I, as the customer , am being held responsible for this fee. Over the past 3 weeks I have made numerous attempts to resolve this issue by contacting MTN via calls and email. Unfortunately I have been passed from one consultant to another, many of whom appeared unqualified to address or resolve my query. This has resulted in significant frustration and wasted time , as I have been unable to obtain a resolution.
