Onenumber and *********** service

Several months ago I bought my wife an Apple Watch to use with her iPhone 8 so that she could make and receive calls on the Watch when her Phone is not with her. She was on a Smart S contract and she successfully activated Onenumber. A few weeks later a Vodacom consultant called her and told her that Smart S was being discontinued and put her on a new package. One number then stopped working. It has now been about 3 months and despite calls to the help centre and visiting the Vodacom shop in Baywest several times for help, Onenumber is still not working. The last "help" was to change the contract and she was assured it would work again on 1st February. It is now 3rd February and it is still not working. To make things worse, she is being charged R25 for a service that does not work. From previous experience, the only way to get anything fixed with Vodacom is to put a **** review on Hellopeter.
