The worst service and communication!

I cancelled my Miway insurance more than a month ago via my broker. After Miway deducted a premium AGAIN this month that was not supposed to happen, I asked my broker to investigate. After he did and cc'd me on all e-mails with Miway, it so appears that the cancellation was just ignored.... He was in contact with Tyren - apparently from the brokers division. All of a sudden Miway is trying to make contact, via phone calls, sms, emails - anyway they can (keep in mind, not when the cancellation was requested). I actually answered a call late yesterday afternoon from them - I explicitly told the lady NOT to speak to me, but deal with my broker, this was cancelled already. My broker e-mailed an cc'd me again on e-mails - Tyren being the contact at Miway who advised they are trying to get in contact with me - this after my broker specifically said I will not answer calls - Miway must work via him and this was cancelled already. Again Miway phoned me 10 minutes ago - Simpiwe Kumalo - telling me he is from the cancellation department (explaining it's a different department than where Tyren is. I do NOT care as a client - you clearly have communication and client service problems. After explaining AGAIN to deal with my broker - he asked me his details...... - So Tyren who was the contact all along did not give through any instructions/details. 5 minutes later he tells me he is looking at the email now and can see the instruction from the broker - so he DID have the brokers details.... Miway MUST refund me for this month premium they incorrectly deducted urgently and CANCEL my policy - nr ***4. I will NEVER advise anyone to insure with Miway again.
