Empty promises

I called into the store to check if they have the Junior's boats (new design) and they confirmed that they have it. I asked to put aside size 5 and 6. when I get there size 6 was unavailable and I asked if they can get it from another store and bring it to Sandton store which this was the 28th of November. I have made a lot of calls to the store and promised I would get it on a certain day but nothing arrived. I get excuses that the other store have sold it after they made a booking and the driver did not get the chance to collect the shoes what bull **** is this!!! This is unacceptable as I am also a customer who is paying. Now I have my other son crying all the time as he does not have the same boat as his younger brother. What is the point of ordering customer shoes in other store if we will never it, this is unacceptable for me to have waited 2 weeks for them and still I have not received anything. Timberland has to improve their services..
