Subb standard products supplied

On recomendation from a friend we approached this business to supply us with clothing for my daughters wedding that was a month away. The owner sent us a quotation and never supplied a invoice for the materials or the service. We were happy with the quotation and gave the go ahead for her to proceed with this order. My mother and I drove to the Pretoria branch to have our measurments taken and view the suit that was available for rental for me.A picture of the dress my mother wanted was give to the staff after measurments was taken and we discussed that soft material should be used and that she would be able to use the outfit for other occations. We where assured that this is possible. A few days later my wife and mother visited the Potchefstroom branch and the measurments was taken again and everything regarding the dress was discussed with the owner we even supplied a picture of what we wanted the dress to look like to the owner of the company. The owner of the company supplied us a sample of the material and this was accepted as the material was soft. They could not supply us with the material and assured us that they had a suitable replacement that was very similar to what was suggested. A photo was sent to us via whatsapp of the material they intended to use for my mothers outfit. We had some objections as the image had a greenish reflection and did not look like what was suggested. She assured us that this was a good option. My mother and I went for fitting about 2 weeks later. My mothers outfit was way to big and the material was very heavy and caused irretation on the skin as they did not put any lining in to protect her skin against the abrasive texture of the material that was used. They assured us that they would fix the issue. A few days later we visited the Potchefstroom branch again to fit the suit i would be renting. They had to yet again take measurments as the suit was not properly tailored as per previouse measurments taken at the Pretoria branch. My mothers outfit was again discussed and the owner assured us our concerns would be adressed and the end product would be what we asked for. The owner assured us the outfits would be ready for collection the monday before the wedding in the event that a final adjustment on the outfits would be needed. They did not keep to the promise the owner made and we only received the outfits on the Thursday afternoon. We immediatly started to fit the outfits and saw that the alterations that was made to my mothers dress was totally unacceptable and photos was sent to the owner. My rented suit was also not as per the measurments that was taken by them twice in two different locations. This was also communicated to the owner via whatsapp with pictures. We had no time to go back to them as wedding proceedings already started the following day. I had to make a plan and purchase pants for the suit and the undercoat was unacceptable to wear for a function like this. The owner assured me that she would make this up to us as this is not on standard. She admitted on whatsapp that they had made a mistake and they would compensate me for the bad quality of the outfits. Till now we could not come to agreement and the owner is not willing to come up with a solution to my issue. I have raised this with her on whatsapp and via email. We also made the mistake of paying this company up front for the outfits.
