I took in my cellphone to Edgars store landros mare street branch in polokwane for repairs on the 13th of January 2015, i was Informed by the shop assistant that i should come to collect my phone three weeks later.Three weeks later i was informed that the insurance required the battery, offwhich during that period no body communicated with me that they needed the battery only when i came to enquire about the battery i was informed that they needed it, i was informed by the shop assistant that i must come back after one week to check my phone, i did that a week later the phone was still not back at the shop and i was informed to come back today on the 17-02-15, when i got there at the shop the phone is there but the battery is no where to be found after countless attept to speak to the team leader at the finrite call centre to enquire about the phone the call centre agent kept on telling the shop assistant that they need to investigate the mater , i waisted three hours of my time at edgars waiting to get solution to this , i even requested to speak to the manager , the department manager came to speak to me without even solutioning my problem, pure incompetence .
