Worst service I have ever recieved

I took my Samsung device to the repair centre as I thought they would provide a quick and professional service,how wrong I was.- went it and requested that my device be repaired ASAP.I was promised a qoutation in the nest 3 working days.I called many times n even went it to follow up.but I received my qoutation 1 month and 10 days later!when I requested my device back as I refused to be subjected to customer service agents attitude and porr service.after an uphill battle I was told I need to pay to receive my device back even though no service or repair was rendered.ontop of receiving a crazy qoute of 3000 for a reboot issue.today o stood 30 mins behind 5 customers to speak to some1 in their centre.I would not recommend this service or Samsung to anyW due to their after sale service.
