Rude, arrogant, disrespectful wurm of an mtn manager

My husband and I went to mtn Umhlanga (the one at Coastlands Hotel). I had recently upgraded and my husband took over my old phone. We did a sim swop and I also had an issue with my brand new screen protector that was fitted, which had already have had to be replaced twice by mtn because of bad quality issues. The lady that assisted us was good, helpful and professional, but had to call the manager to deal with my screen protector issue as I got my screen protector at the la Lucia branch. This was the second one I received in these 3 days as the first popped off, and you can barely type as its so hard and a really ****py brand. I wanted to change it, as I wasn't happy with it. Well, he didn't come and speak to me directly, he just told her to tell me the answer is No and to go back to La Lucia. Which is a major hassle for me as my husband uses this branch and I honestly didn't feel like driving all the way to LL on a Sunday. Besides its all Mtn... I told her that I had just renewed my phone 3 days ago and its still under 7 day return policy. If he can't speak to me directly and also make an effort to assist me, I might as well return the phone and cancel the brand new contract and go to another service provider. He eventually came out with a massive dismissive attitude and very arrogant. Told me very shortly I must go to La Lucia. I asked him again if he can't just help me and he again very shortly said No with a ****py explanation. My husband at that point said to me in front of this rude man, to just leave it and that he will take me to La Lucia. This man as arrogant and rude as he is, doesn't listen and starts talking over my husband by which time my husband gets upset and asks him if he's deaf as he just said to me we will go.. Then he starts attacking my husband and asks if he wants to get violent - completely ridiculous response. I then asked him what his name is, as I'm going to report him. He flatly refused to give his name and called security to remove my husband. Before the guard touched my husband, we made it very clear that if the security officer touches my husband without due cause, there will be a civil case opened up. The asshole manager then called him off. At that point we then left with this ********** manager still shouting at my husband, both having words. He purposely was trying to aggravate the situation and cause a scene. This over a R300 screen protector. I will be cancelling my new 24 month contract with mtn tomorrow and going somewhere else, being an mtn customer for 15 years clearly doesn't mean anything to a worm like that. Mtn will never have our business again.
