Bribes taken at Telkom for phones

I am appalled at the lack of service and arrogance of the Pavillion Branch assistants. About 3 weeks ago, I signed a contract (I have 4 contracts, including 1 prepaid with Telkom) and chose my phone. It took them 3 weeks to get the phone and then they called me on Wednesday afternoon, 30/01/2019 to tell me it had arrived and that I must pick it up the next day or as soon as possible. The next day, Thursday, 31/01/2019, I took leave from work and rushed from Pietermaritzburg to arrive at Pavillion Telkom around 3ish. The woman there told me that she had already given the phone to someone else. Please tell me what bribe must I pay to Telkom workers in order to secure my phone??? It seems like they take money on the side and then issue out customers belongings to either their friends or for cash. Or maybe to someone of the right race??? I can't understand how they can give my phone which I ordered so long ago to their friend in exchange, obviously for a bribe!!! Can someone investigate as I am very upset. I was a loyal Telkom client right from inception of 8A and I have made all my family, including children to take out Telkom contracts. But the service is pathetic!!! Can someone give me a call to investigate my complaint and put right this blunder and dismiss the workers who so greedily take money in exchange for phones that belong to others???
