Watch repair

Took my watch in for a replacement strap in May 2015. Received the watch after waiting patiently for eight weeks. Within two weeks of using the watch the strap broke and almost lost the watch, again I had to return it to the store for repairs. Approximately eight weeks passed again and received the watch back and sadly after one week the strap came undone again. On returning the watch to the store for the third time, now irate, I was informed by Tertia the Supervisor that there was absolutely nothing they could do but send the watch in again and wait for it to be repaired. I thinks that this is unfair & unjust that I have to be inconvenienced each time after paying for the repairs and waiting patiently. My next step is to seek advice and assistance from the Consumer Protector as I am extremely annoyed and unhappy with the 'don't care attitude' of this retailer.
