Vodacom 4U - Cape Gate- Bad customer service

Poor and rude customer service at Vodacom 4U store at Cape Gate, after waiting 2months for a device to be repaired, no communication from this store wrt the device. I went back to find out when my device would be ready, just to find out the device was at the store and nobody bothered to call me. They were full of excuses and I was not impressed with their lack of concern. Then an assistant by the name of Jaco brought the device and told me they are replacing the device and as I was telling him my dissatisfaction in their service he just shoved the device at me and told me to get out of their store. Never was I humiliated the way I was that day. I was livid...... I sent a complaint via e-mail to Vodacom's complaint dept on the 28 April 2018. I received no response from Vodacom. I resent that e-mail on the 24 May 2018 again no response. I so sick and tired of bad service. I went to another Vodacom store and told them of my ordeal, the response from that consultant was that so many clients came to their store complaining of the that store. What is Vodacom going to do about this..
