Tygervalley not returning item and customer service non-existant

Incredible connection Tygervalley has shocking service. I took my phone to Joshua on 21 July (very friendly and curteous), was told it is under warranty and I'll get my phone back fixed or a new phone. I explained emphatically how necessary it is to get my phone back swiftly for work purposes. 5 August I followed up, suddenly there is water damage to my phone according to your external supplier and a ridiculous price of R3750 was quoted for a phone for which I paid R5999 2 months earlier to fix, ridiculous. 6 August I emailed Calvert Boer to let me know when I can collect my phone, I am not paying for the ridicuous quote. Still today 31 August, I do not have my phone back and the store does not have my property. This is the most appalling service I have received, not once did they store get back to me on their own, each time I had to ask and ask and ask. The item does not belong to Incredible Connection and a customer should not have to go to public platforms to get their property back.
