Disappointed, regret, poor service

I am so disappointed, frustrated and I feel like I am being ****med by Go solar company. We signed a contract with them from June and we agreed that the solar system was for the lights, appliances and geyser, we are paying R1740 per month then we buy eskom units for the stove for cooking. I have been doing that way until last week on the 29th of September when we left the house in the morning we had units on our electricity box and when we came back around 8pm there was still units then 9pm the lights went off everything shut down when I check my units they were on zero but my concern was why the lights and my appliances are not working because my solar should be the back up. I bought units for R300 and then after put them on the electricity box the solar system was did not pull up it shut down and up and that was a concern because now it is affecting my appliances. The next morning which was the 30th of September I called Goslar for assistance because firstly now I am frustrated because I am no longer using the services that I was paying for at gosolar I am spending more money have to buy eskom units, now I am told about the app system of which the time we were enquiring about how does this system work, we were told that they will come and install the battery, inventor and the panels because the solar system works with the sun and at night or in an event where the whether is not hot then the battery will work to sustain the power so that you have electricity in your household, then now I told them that I don't have the home wi-fi because I was never told that their system is using the app so I should have home wi-fi because if that was the case I wouldnt sign with them as I was trying to save the costs from eskom, home wi-fi for me is extra cost, so they send someone to check on what was the problem because I insisted that there was a problem with their system. They found out that the inventor was faulty and it needs to be replaced, the whole of last week I was calling gosolar using my money to call and buy more electricity because the eskom units have gone up and is expensive to keep buying while you have already paid for the solar that is not working and Goslar staff is taking their own time to be of assistance to you as a costumer and on Friday which was yesterday they send people to come and install the new inventor I had my units on the eskom box but this morning I just woke up around 6:30 am and the lights are off, appliances are off again I called the Goslar because now it looks like I am begging for the system that I am paying for every month, I have already bought units for R700 since the 29th up to today and who is going to reimburse me my money, I have paid R1740 to Goslar already for the month of October but it is not working. Can I be assisted today or Goslar company can they please take back their system out of my house because clearly they don't want to assist me I am only paying for nothing and they are decorating my house with the solar panels that are not helping me. I am very angry and disappointed because I have spend the whole week calling gosolar offices, calls were transferred and they will cut you off before assisting you and you call again they will tell you that the person you looking for is not in and drop the phone while you still need to get someone else to assist, there was too much wrongs and rudeness as I am saying I regret why did I make this decision of using Goslar and if this issue is not resolved by today I will report Goslar to consumer ombudsman so that they can take over the matter.
