*****elent Sales frim Vodacom supplier

A while ago someone phoned me to give me an upgraded offer on my Vodacom Wifi Router because they see Im a good customer and that they only going to migrate my current contract to this new ons? Then when everything arrived all seems good untill I asked is it now migrated? Then they informed me it is a new contract? On the phine call that was recorded they heard the operator told me that it was going to be a migratiin and not an new contract but for the past 6 odd months Im paying an extra contract although I caceled it as soon as Ibrealized the operator **** to me Now they came and fetch the device already but still Im paying and they said they will refund me? This is still not happenning?
