Disappointed and angry

I took out a contract on the 27 June 19, at northgate mall, an agent there assisted, I indicated that my number was on contract just migrated to prepaid it must be Rica, he said no problem, before I left the shop which took 4hours me being there, he said he will log a call for the number to be active,the following day, since it was around 4:45, on the 28th around 3pm I phoned to ask about it, I was told he went to lunch he will phone me, which he never did I tried around 4:30pm there was no answer, the following day o phoned a lady told me according to her system it is fine, my number is not active till today, the staff are so unprofessional in that branch the language they use and etiquette is disappointing. I am not happy with this
