Poor service, terrible workmanship

I requested a qoute for two sliding security window(gave them measurement) on the 21 June 2019. Qoute was R7087.00 and paid R4000 deposit on the same day. On 25 June i was told that they misqouted it was suppose to be R10805.81. I wanted to cancel order however they gave me discount of R1305.

On the 14 August I was asked to the outstanding amount and I paid R5000 since the delivery was schedule to be 19 August. On the date of installation, I received a long excuse story. I told them their service is poor. I took a day off at work to be present as there is no one at home.

They came following day, one sliding security is not installed as requested. They said will come come on 13 September to rectify the problem. Another excuse was made. Even today it is not fixed.

The sad thing is I am the one who following up, they just sit back.
