Necron bad service

Middle of February 2021 a contract was pushed in my hand at my door by Necron and was told to sign it and my rent will be R4500 a month and not R4840 and my rent will go up every year by 7% next year. Two months my rent was R4500 and all of a sudden R340 was deducted for the month of April and May and my rent was R4840 again. I did e-mail Chantel couple of times to explain why this was happening but she ignored all my e-mails. I took a photo of the contract before I gave it back the same day to the person working for Necron. My mother was also whiteness to this. The 4th of May I bought R700 electricity for my pre paid meter because to buy every week you get less units. On the 13th of May I was told at my door by the caretaker the pre paid meters will be removed and I must be reimbursed by RMS. I was not given a month notice and was told because of my complaint my rent will go up by 10% next year by Dayne. RMS told me it is not their problem and I must be reimbursed by the owners of Hemmingway Heights Vanderbijlpark. Still my two issues was not resolved and was charged R700 for electricity on my rent for June. I use R450 electricity a month, new pre paid meters still not installed. I was R200 short on my electricity and was handed a written warning at my door legal steps will follow should I not pay the outstanding R200. They also switch your electricity off as final step. Never had I such bad service from a estate agent as Necron.
