useless service

We send a letter on a letter for a number to be cancelled, on the same letter requested a swim swap, Vodacom went and cancelled the number of the sim swap. On Monday we phoned to get this sorted and we followed up with Kyle and Forgiveness and still it has not been done. It has has been a week now and still no service. we have to pay airtime for our employee. please can someone get back to me on this matter urgently. Your services on this matter has been pathetic.
