Poor returns service

I returned a pair of Caterpillar shoes on 30 September within 3 months of purchasing it because the upper was coming away from the sole. After 4 weeks I received a phone call from the store stating that my money would be returned. I explained that this is far from ideal for me as I bought the shoes on sale and would not be able to get an equivalent pair for that price. The gentleman on the phone promised to try and find an alternative solution and call back within two days. I never heard back from him. I managed to get hold of the new store manager who promised to call me back the following day. This also didn't happen. Eventually I managed to get hold of him on the phone. He informed me that someone has now decided that my shoes need to be repaired but he cannot guess when I will get my shoes back. I will feasibly have spent two months without shoes when/if I eventually get them back and they are functional and I've had to use an old substandard pair. I have always enjoyed my experiences at Cape Union Mart, but this has left me very disappointed.
