Over Billed

Consultant loaded the incorrect contract that was initially app**** for. Few days later I was billed twice (for the correct amount & the incorrect amount). Upon querying this, the consultant assured me that the refund of the incorrect amount would be credited into my bank account within 14 days. It is now day 14 & nothing from vodacom has credited my account. Upon following up the consultant now says the funds will be credited to my vodacom account instead of my bank account. Upon calling vodacom they have confirmed that no credit amount is due to me by them & that this must be taken up with the store. This is extremely ********* & poor service levels.
