If you say you will call back then CALL BACK!!!!!!

On 7.05.2015 I called to upgrade a Business phone, I at first picked the wrong package (Smart S) & then an hour later changed it to the correct package (Smart M), I was told that the 1st phone (which was dropped off on the 8th May) will need to be collected so that a new phone with the correct package (Smart M) can be delivered. 3 WEEKS later and 13 (THIRTEEN) calls from me to *** later and still NO correct phone. The 1st Phone was collected on the 14th Day since my 1st phone call and I was told it would take 24-48hrs for the new phone with the Smart M package to be delivered - today is day 3 since collection & NO phone. for THREE weeks I have been chasing Vodacom staff, 1 out of the 13 phone calls has someone actually called me back. You are in the business of communication so COMMUNICATE! Where is the correct phone? - I cannot speak to anyone at *** because I keep being told someone will call me back - THEY DON'T!!! its been 3 weeks, yet the 1st phone was delivered within 24 hours! I called at 08:38 this morning, I was told a Supervisor would call be back - its now 13:15 and NO PHONE CALL! even your supervisors are not calling back or sorting this out!
