Wrong sized kitchen unit and poor communication.

I enquired about a kitchen unit in Bradlows online for a kitchen unit to be fitted in my complex, they sent me a Guy to take measurements on the 26 October, then Guy gave me a qoute then said I must put 80% deposit which was around R20800 and I did they told me they need 14days to order the kitchen unit the within that 14days they will come and install the unit, I told them no problem as the was still a tenat in my complex that time, then on the 3rd of November the Tenant decided to move out then I told the they can come and install as the tenat is now out, my 14days as per their invoice was on the 13th of November so I made appointment with them to come and install, it was difficult to communicate with them as they told me they not sure about Friday the 13th but they will communicate if they come, I tried to get hold of them on them on the 11th to remind that they must come on Friday to install the kitchen unit as I need to move in on the 14t h and I have a small baby I must make means to come on the 14th when they finish so that I can clean and move in on the 15th and they only reply rep**** late at night to my watsapp message saying they are waiting for their manager to hear if the will make on Friday the 13th, I waited and waited and when they finally rep**** they said they will come on the 13th November Friday to install, their invoice said One day service and I was happy that they will finish in one day then I can clean and move in in time, but on Friday they only communicated with me in the afternoon and I went to see if they finished to my suprise they came with unfinished fittings and they just left the kitchen unit on the floor without out installing I have pictures to prove what happened that Friday, they said they will come on Saturday to finish the unit and I went on Saturday late to the complex to check if they done, when I got there every thing was a mess, the kitchen unit doors were not closing, the doors were cut wrong not straight everything was a mess, I tried to get hold of them and they said they will come on 15th to fix it's small problems it will take only 4hours to finish, but they never did but instead kept on messing every thing up I had to go and leave with my mom for them to finish, my kid didn't go to school as we were now far, from school, they sent me message that I can go to complex and move stuff in on the 17 November and when I got there I couldn't believe that after so much trouble they put in and inconvenience me and the kids that the kitchen unit was not still yet complete, they told me they will come on 23rd to fix the doors but never came and communicated with me on the 27th of December that they will come on the 30th by that time I already moved out again from the complex and went to my partner with the kids for December holidays and the unit after a long month of November running around still not complete but they have taken my R20800 deposit, they used electricity every time they came and still messes things up, today is 1st of December my kitchen unit still not yet done I dont know if they've taken advantage of me because I am a woman and had no one to help me with them but it is was I encountered, I dont know what to do anymore as My money is gone and the so called 1day service took the whole whole month of November and still not complete even now as I am tired leaving the key with security for them to use my electricity and still mess things up, I need my Money Bradlows this is not what I expected from you when I enquired I left people from my community who could do a kitchen unit for me but I thought since you a Good shop with quality I should go with you but I regret every enquiring to you, wasted my time, inconvenienced my kids and wasted my money, I would not recommend anyone to you, Just want my money back and take your messy kitchen unit out.
