SHOCKING AFTER SALES SERVICE

I've done an upgrade with Vodacom, beginning of Jan. Received my phone within 3days. After going through the phone decieded that i did not like it and called Vodacom immediately to return it. They told me it will take 7-10 days for Ram to collect. That was 11Jan. It is now the 18Feb and I am still following up with Vodacom as to when they collecting this phone. Not once have I received an update from After sales regarding this. I have to call them each time, only for them to tell me that they will send a follow up email to the collections department. One would think they will update you to advise what the delay is once they receive a response from collections department. Besides all of that, even after it was logged that I am cancelling my upgrade, they still allocated the free minutes and Data for the new contract. Its like they wanting me to use it and then charge me for it. IM SO ANNOYED !! I can never speak to a supervisor or a senior member. What happened to VODACOM's customer service in this country, its just getting worse and worse.
