Unhappy with service

So last week Tuesday I had the unfortunate event of having to go to tyremart boksburg to have 2 tyres replaced as it was a matter of urgency. I was assisted and quoted, I specifically asked if valves and balancing was included,I was informed that they don't charge for that extra. I asked the sales person how long it would take as I have deliveries to do. I was told that it wouldn't take long. Granted they had to go fetch the tyres my vehicle required. But time was a factor. 1hour and 40min later I was able to leave. At my last stop I decided to inspect the work done and discovered that the valves had not been replaced and we're badly perished. I drove back to tyremart centurion where I informed them of the situation and paid for the replacement of the valves and balancing to be done again. To my surprise I was informed that balancing was also not done. I then decided to send my review on their official website and have still not gotten any communication from the site based on my complaint. I thought I'd give then chance to assist with this matter before going to hellopeter but that seems that it did not work. If it were not for the great service and advice offered by the Centurion branch I would no longer support them. As I have a delivery business attention to detail is extremely important as my vehicles carry weight as well and a small thing like this could have had serious consequences... very unhappy that I had to pay for certain things twice...
