Disgusting operation at Defy!!!!!

I am very frustrated with the service department at defy. You can not speak to anyone, they do not connect you managers and you are not allowed to talk to any technician. I have been dealing with Ishmael Mosweu. Fistly the part they ordered took 3 weeks longer to arrive then promised. The they say a technician will call to wednesday the 27th of march to make appointment. He never called and we found out at 3 in afternoon after calling again that he was there and we were not. Must we just sit at home? This whole week Ishmael promise they will now come wednesday 4th of April. Now we wait for them and nobody arrives the whole day. After phoning continuously and ongoing promises of phoning as back they now say it will be next wednesday. I do not understand why they cannot get their act together. They take no accountability for their actions and we have to continue wait for their lies.
