Review Trye missing Falken make

Hi i had my car serviced at Kia Tokai CapeTown on Friday 30 July. I asked for a quotation to replace 2 tyres. It could not happen because the phones were down. I went to Goodhope Tyres on Saturday 31 as I replaced 2 tyres earlier in the year at their Centre. When I arrived there to obtain a quote, I noticed I had only one Falken trye on the front wheel. It should have been 2 Falken tyres on the front wheel. The one Falken was replaced with a Kumho Solus. Plse can you replace my trye as it is only a few months old bought at Goodhope Tyres. Im working from home so my car is in my garage most of the time and was not at any repair centre for it to go missing. Waiting to hear from you soon. Cell 060 564 5670.
