vodacom WORST SERVICE EVER

Good day on monday the 30th April i took my dad to the vodacom store in Eastrand mall to upgrade his 3g modem to something better so after much delay due to lack of interest the sales consultant by the name of Khaile finished all the paper work so i asked her if the new devices need to micro sim or nano sim as the sim we had was old so she then informed us that we need to do a sim swap which we did when i asked her how long she confirmed that is takes 4 hours so we head home and wait for 4.5 hours still nothing so i phone the call centre to find out what is happen they then inform me that it was still pending on the stores side so i would have to waiting until 1 May which i did at 10am i check it again but still nothing so once again i phone it to the call centre they then told me that the sim card must be out the device for 4 hour ok so i remove the sim card and wait till 14:30pm still nothing once again contact the call centre how they tell me a sim swop takes 24 hours which mean it would be working by wednesday so once again we wait on wednesday i get a call from vodacom to say they it is being process and it can take up to 24hours as that department does not work on public holidays we are now more than 72 hours down the line still nothing wednesday goes then i get told that all will be working by friday for sure so friday come still nothing we are now 1 week later and still nothing this is the worst service i have ever seen every person u speak to gives u a different story and as for the store not worth wasting your time as they are to busy and never return your calls
