MTN Consultant turned me into "hahahahaha" literally!

Can't believe I was so stupid... I am a joke... I am "hahaha"... MTN consultant called me on the 10 or 11 of March claiming that MTN wants to "Thank me" for being a good customer, that alone should have surprised me. He went on to say that MTN has selected my contract account to be moved to a different contract where and I quote "I’ll be saving from my monthly contract fee but I will be getting more voice minutes and Data". He further went on to say that I would be paying less because MTN is thanking me.Fast up: My debit went through last week and my fee had gone up drastically than what I used to pay ,that’s when I knew I was ****med.I did not give you consent to migrate my contract you are misleading customers MTN. TO think that I wanted to upgrade in few months, now that chance might be gone because I was migrated by being ****med. Please take me back to my old Package MTN South Africa.
