Data error

On the 24th of February I transferred data to an incorrect number. I contacted MTN to ask if they can rectify the error and the lady that assisted me told me if I faxed through my bank statement reflecting the transaction they would be able to assist.<br> I did as instructed and it was not rectified so I called them again on the 27th and the lady I spoke to said she will send a mail to Grace and get her to call me back. There was no call and my data was not there.<br> <br> I called them again today and the lady I spoke to tells me that the person I had transferred the data to has depleted it and there's nothing they can do now. <br> 11 days later, they can't help me. I had informed them in time for them to rectify this.Granted it was error, however as a service provider they have an obligation to assist when things go wrong.
