Terrible service from Madonna

<p>I've been getting assistance from Madonna based at MTN OWNED by the Nedbank Campus in Sandton. Her service has been so **** horrible. I've been there 4/5 times and left my number there for her to call me, but she hasn't even called. NOT EVEN ONCE! My contract was approved in June to get an IPhone SE 64 GB; a month later, I was still told that it is not available. I later changed it and requested an IPhone 6s. I have walked into that store more than 3 times after my request, leaving my number with Madonna's colleagues because I wouldn't find her. She has never even bothered to call me regarding my request. I went there this morning, and she still hasn't call me back. I mean what do I have to do to get a phone?? This is such bad customer service. How many times do I have to walk in and out of that store? I asked her colleagues to assist instead, and they told me that they cannot assist me; only she can do that. I mean if a consultant can't help a customer, isn't the available one supposed to assist?</p>
