Terrible customer service from Edgars Centurion Mall

On the 23rd October 18, I took in the cellphone smart phone ZTE for repairs. two weeks later I found out that Mxolisi the cellphone counter sales person told me that the phone had not been collected by the supplier as yet and gave me the supplier's contact details to find out why they have not collected the phone and they wouldn't talk to me as I am an Edgars client . Then Jerry the manager from the cellphone counter advised me that the phone had not been booked through that is why it has not been collected and he will try to expedite my query . I kept calling back the store but still have not received a feedback. I spoke to the store manager Edgars Centurion Mall 26th November 2018 and he still have no answers for me. Not having a cellphone for a month is a huge inconvenience and I still don't have it.
