If anyone understands how massive a problem corporate fraud is, it's Jabulani Mogale. He's a fraud investigator with one of South Africa's biggest companies, which makes his MultiChoice experience more than a little ironic.Mogale bought a second decoder from Makro in early May, to benefit from MultiChoice's Xtra View functionality.All was fine for a month or so until one day, without warning, both decoders stopped working.On querying this with MultiChoice's call centre, he was told his account had been suspended "due to fraud".More than that no one in MultiChoice's call centre would tell him, initially."I was then put on to the fraud department, but when no one was able to help, I drove to their Randburg office and finally spoke to someone in the fraud department who told me that my decoder had been stolen from a store in Pretoria in April, and its serial number had been flagged on the MultiChoice system."I produced my receipt from Makro, but my service remained suspended," Mogale says."But why didn't the fraud department contact me to discuss the issue before suspending my service, not only on the 'flagged' decoder, but both of them, leaving me with no DStv at all?"And why was there no alert put on my account, so that anyone in the call centre could have helped me with accurate information instead of repeatedly fobbing me off?"A MultiChoice spokesman told In Your Corner that Mogale's "flagged" decoder was one of 50 decoders stolen from Home of Living Brands, which has opened a case of theft at a Pretoria police station.So how did he come to buy a stolen decoder from Makro?Well, he didn't."The serial number on the Makro receipt he presented to us is different from that of the second decoder which was installed in his home," the MultiChoice spokesman said."Mr Mogale used an independent installer, not accredited by MultiChoice, to install his new decoder. It appears decoders were swapped during the installation."That news floored Mogale, who has used the installer's services for many years."His bakkie has MultiChoice's stickers on it," he said.But MultiChoice says that is no guarantee that an installer is accredited. The only way to be sure is to check the list of accredited installers on DStv's website. (See below)Naturally, I asked MultiChoice what had become of the other 49 stolen decoders."We are aware of some of the decoders but at this time we cannot give further details that might compromise the ongoing investigation," the spokesman said.She couldn't say when the investigation would wrap up.Mogale's service has since been restored. And as compensation for the runaround he got when trying to get to the bottom of why his service had been suspended, MultiChoice is to reimburse him for the second decoder he bought to replace the stolen one which his installer allegedly installed in place of the legitimate one he'd paid for."We would like to apologise for the type of service he received," the spokesman said. "This is not the kind of experience we expect our customers to receive."We appreciate his feedback and have taken the necessary steps to ensure that our customers do not experience this type of service again."CONTACT WENDY:Email: consumer@knowler.co.zaTwitter: @wendyknowler..
