Absurd customer care

I went to Mtn website looking for a data contract and got the R199 on a month for 40gigs of data. Filled up the relevant forms a ya after I got a call from a lady to ask about my details and finish my application. Two days after I got another call from a different lady this time she also wanted to to finish my application for me, I told her I had already done that but as she was checking on the system she dropped the line. Two days after that I got another call with a different lady this time also offering to finish my application for me, I dropped the phone on her because wow. I kept getting calls from that same number I would just ignore them. Please Mtn if you don’t want to give me the contract can you stop your angents from calling me.
