Very unhappy - Call centre zero

I got a call from Mr Price call centre stating that because I have a Milady account that I can get discount airtime on my account. I spoke to Michelle (call centre agent) and advise that if they can just call me after 16:00 as I have a meeting to attend. At 16:44 I received called from you and was unable to answer due to certain reasons at the work. Please note that there is a huge different between 16:00 - 16:44

Today I had a busy day at the office and from 09:00 - 11:45 I had received 10 calls from your agents. Only after I answered the last called and informed Michelle that I have not interested in the special did the calls stop. By the way Michelle was rude and I told her that I was not interested in any offers at moment but she was just trying to not to take no for an answer. Eventually I had to raise my voice to say that I was not interested and said goodbye.

Surely 10 calls is pushing the limited. If a person cannot answer at the time don't try again until later.

I really do hope I get feedback, unlike the last time where I submitted to customer care a complaint which was promised that Milady and Mr. Price will be combined and that you can either use you account card and any of the store. Which I am still waiting for feedback even if the call centre advise that this was going to happen very soon (2016)
