I want my speaker back!

Hello Peter<br> <br> My brother bought me a JBL speaker from the i Store in Sandton City last May. 4 months in the speaker stopped charging and i forgot about it. Recently my brother reminded me that it is now almost out of warranty. I took it to the store with all the receipts, accessories and packaging. I was told it would take 3-5 business days to find the fault and give me next steps. After 6 business days i sent a mail asking for feedback... Nothing. I sent another one another day... Nothing. It is now almost 3 weeks since i booked my speaker in for service. I would like my speaker fixed soonest since I'm emigrating this weekend!!! Somebody from Apple please give me some feedback. I expected better from such a reputable company,i would expect such from some Mickey mouse operation. I was not even given a reference number and i was told an email is sufficient communication when i need feedback or in case of delays. The customer service at the store is generally amsybal. Istore i want my speaker back and i want it fixed. I was always going to take responsibility if it was found to be my fault but i think we have now crossed that point. Somebody give me feedback please! !
