My two year nightmare with Cell C!!

Little did I knew what was waiting for me when I took out a contract with Cell C two years ago. This is when my nightmare started. I had a cellphone, yes, but no cell phone reception. I could never have a proper conversation with anyone. Either I had no signal or it was really bad. I could hear them, but they could never hear me. I was scared when I was on our farm alone, as you never knew when you had to phone for assistance. At last!! My contract expired on 9th June 2015 and I thought my nightmare was finally over. I went on Saturday to Cell C Key-west to change my number to a prepaid to enable me to move. Walking into the store, the atmosphere was already cold, no one that was really interested in helping me. At last one guy asked what I wanted and he promptly told me he cannot assist me, I must phone the customer care number for assistance. I immediately whilst I was in the store contacted them and was greeted by an answering machine, only open from Monday to Friday!! When I told the guy he just shrug his shoulders. Yes it is true!!! When I phoned this morning, they advised me I must give one month's notice!! My nightmare continues!!!
