Rude and disrespectful and very much arrogant service form Vodacom

I had the most arrogant, very rude and disrespectful customer service in my life from a Vodcam store consultant in the East Rand Mall. Yesterday I went to the store to do a swim swap the consultant by the name of Mariann Selwane helped me she tried to perform the swim swap only to find out that the account 1 is a contract with BLC and it's in areas. Therefore she can't do the swim swap as the system is not allowing her she needs authorization I asked in her in this instance what happens she told me she doesn't know I asked then who will know ? She told me I must try Vodacom hence I'm in a Vodacom store! I asked for the phone and called Vodacom on their 082153 number the lady that I spoke over the told me it's very much possible to do a swim swap I just need a letter of authorization from BLC stating that we can perform the swim swap then lady proceded to connect me to BLC I spoke to a lady by the name of Tebogo Gwangwa I explained my situation the understand asked the relevant question then gave her my email then she sent me the authorization letter. I explained the to the consultant Mariann what transpired in the call from Vodacom witch even before I finished my explanation she told its impossible and I asked you haven't even heard what I have to say she told me again I know what they told you and believe you me it's impossible. I forced her to listen what happened then she asked what do I expect her to do with the letter cause the system this that and that I asked her can't I call Vodacom again hence they are the one that told me it's possible to explain to this lady cause it seemed like I was the one saying it's possible o called Vodacom again spoke to a guy by the name of Tshepo explained the whole situation over again and asked him if she could explain to the lady what needs to happen and gave over the phone to her she spoke to the Tshepo over the don't really know exactly what Tshepo said but all i can hear was Marriann reiterating to him that it's not possible and subsequently dropped thr phone and told me again that it's not possible then told me it's best if she calls the manager by the name of Tarrin Court. The lady did arrive Mariann explained to Tarrin witch half the information she told her was wrong I explained a bit to Tarrin she quickly understood and asked to see the letter Tebogo had emailed in all this time this lady Mariann insisted that performing that swim swap was very much impossible even though I have a letter that clearly states that it's an authorisation letter for a swim swap witch she did not bother herself to even look and the letter. Tarrin then called Vodacom and explained to them the issue and to my suprise now the swim swap was possible. Then Tarrin left me in the hands of Mariann witch now I could see she was really now ****ed off , to top it all of she tells me that Vodacom will call me to explain I don't know what and I must put in my sim card late in the afternoon I ask what time in the afternoon she tells me whenever I feel it's late okay and if it doesn't have net work I must remove the sim card and try to insert it again tomorrow morning I asked her again what time in the morning her answer when ever I feel in the morning okay. I left the store to call Vodacom again as i didn't trust what she was saying to my suprise I can insert my sim after 3 hours witch I explained to the consultant I spoke to that the reason I'm calling is because i didn't trust Mariann and my suspicions were right. I write this very much disappointed I went back to the store again today to complain to Tarrin about that ladies behavior and attitude and it didn't sit well with me
