Denzil Maistry is definetly not Branch manager material.He never returned my numerous calls and messages following my visit with him.My visit with him waa most unpleasant as he was non obliging, very arrogant and made me feel more stressed.;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ***;562298;357;16;2;0;1;0;0;2;NULL;NULL;NULL;15/05/19 10:16;15/05/19 8:28;Disgusting Service!;9,00E+12;;***;This is on behalf of my husband Ashley Naidoo. I have been complaining to you via Social Media and it seems to be falling on deaf ears. If you visit your Twitter profile you will see all my tweets, dating back to March 2015. My husband ordered 2 phones with you via Social Media and the order was confirmed via telephone. That same week we noticed that the one phone had issues with the speaker. I was on hold with the call centre for so long, that my old vodacom number had been blocked from the call centre as I'd reached my call limit. That's how many calls I made. Since I was now blocked, we went in store where we sat for ages while they tried to help;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ***;592426;1360;17;2;0;0;0;0;2;NULL;NULL;NULL;15/05/17 6:30;15/05/19 8:32;Customer retention;;;***;I boarded a flight from Durban to Johannesburg. There was some issue with the flight and we needed to take another flight. The process was fine and the Mango clerks were accommodating.<br> <br> My complaint is that I missed a flight and had to take another. The only thing that Mango provided was another flight free of cost BUT how do you as Mango expect me to come back and use your services? Its a matter of competition. I'm not saying give free flights for the rest of the year - but find a way in which customers will want to use your services again.;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ***;852135;869737;44;2;0;0;0;0;2;NULL;NULL;NULL;15/05/15 10:07;15/05/19 8:34;Make a sale at all costs;5,51E+12;Hayley;***;I found some lovely spotlights on display at this store. The lights in them sat flush with the end of the fittings and were burning brightly. It looked lovely and exactly what I wanted in my new home.<br> Hayley told me the price of the LED bulbs and I was honest and said I wanted to shop around since they were very expensive. I bought two sets of the fittings, and in fact went back for another set a couple of days later.<br> I did indeed find said bulbs - R36 PER BULB CHEAPER at Plumstead Eectrical. However when my electrician inserted them they did not sit flush against the light fitting, instead they stuck out and were quite unsightly. Hayley insisted that SHE had the correct bulb. I bought one to take to Plumstead to prove the difference. Plumstead's bulb was Identical. I returned to Hayley and asked that she try it in the fitting on display. It did NOT sit flush and she was confused. She and a colleague tried various bulbs until they realized that the bulbs in the display were HALOGEN not LED. She called Ryan, the Manager, who after lecturing me on the evolution of light bulb sizes, advised that the fault lay with me since I should have checked.! I am now stuck with unsightly lights ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ***;851734;689120;14;2;0;0;0;0;2;NULL;NULL;NULL;15/05/19 10:30;15/05/19 8:37;tinkies gone bad;9,31E+12;tinkies;***;I bought a pack of variety tinkies as it is enjoyable I was eating it savouring every moment unti I bit into the sixth and final one which was drenched in oil tasted like a gallon oil I started then throwing up tried to contact the company but could not get a hold of them so I kept it in the fridge it went like a rock now I'm disgusted how can they do that;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ***;376967;832309;20;2;1;1;5;3;5;NULL;NULL;NULL;15/05/19 10:16;15/05/19 8:38;Burger King was more of a burger anticlimax;8,81E+12;;***;This is more of an irritated suggestion than a complaint. I have visited the Burger King at Norwood mall 3 times now, all with the simple intention of ordering a tender grill chicken burger. However, all three times I receive the same response... \we are out of tender grill\"". Why is it so difficult to get a grilled chicken breast? Surely it should then be removed from the menu?<br> <br> Then on the third visit"
