Appalling Customer Service

I am very unhappy with Vodacom's customer service. I called in on the 24th of November for one of the Black Friday specials to upgrade from a 5gig to an 20gig with an HP celeron laptop. I asked the guy to please assist me as I couldn't do it online and he agreed unfortunately I didn't get his name ,he assured me that all is good and that is what I will get. Then I received my laptop on the 29th of November but I didn't get what I ordered laptop and data plan instead it was a 2gig and a Dell laptop . I called in the first time on the 3rd of December I found a lady who said she would escalate this for me by getting me the call recordings and she promised go get back to me on Friday but she didnt . I was eventually now taken to the After Sales Department and I was assisted by Thembile Mvele who said to me it takes 7 working days to get help and I explained to her that my 14days is almost there and according to the cancellations policies it must be done within that time frame. She confidentially promised to escalate the issue to her Team Leader Thembinkosi or Tebogo so they can assist me. I waited until I was blue in the face. I then called again on the 14 to check if she escalated and she said she did but no one called me yet again she keeps saying they will sort it out. I then called on the 21st of December my God,it changed from 7 days to 14days all of a sudden . I then asked her why have one the team leaders not made contact as she promised she said she will make sure they call. They didn't call me at all. I'm so furious because I was taken from pillar to post with no call recordings as promised . I called again on the 27th and I asked for Thembile Mvele some rude lady picked up and they were having a conversation while I was listening to them as I had made an error when. I asked for Thembile,please teach these call centre people telephone etiquette and business ethics they don't have them not to mention good customer service at all. She eventually came to the phone, I asked her what happened she then said the teamleader is not in but will come at 10. They didn't call as usual I then called again on 29th to follow up she put me on hold for long . She then came back to say they will be collecting the laptop but I asked why she said that's what her and her useless Team leaders either Thembinkosi or Tebogo I asked why but she couldn't come up with a sound and reasonable outcome as to why they are cancelling it. I told her that I want to use this for Business purposes hence I opted for the price plan I chose which was a bargain .I'm super agitated because 1. No one helped me as promised too, 2. The team leaders are just as useless 3. I never gotten the call recordings lastly I am not willing to change I want to be compensated for a mistake and carelessness that was done by the Sales hungry call centre agents who are just concermed about closing a deal so they can get their commission. I want a proper and sound reason for me not getting anything for all that has,happened. I hope I will get a call from a person who respects their customers . I hope to hear from you SOON.
