Clone & Cancellation without my authorisation

I went to Forest Hill Sunday past 8th March at about ten thirty. I did a sim swap from a micro sim to a nano sim after having had the previous sim swap cancelled the week before because the technician couldn't even give or recommend me the correct sim card for my phone, sony xperia z3! All this on MY TIME! Which i have very little of! It is now 10 March and i am STILL not able to use my new phone and sim card because Vodacom has had me call in everyday first because my first call was for them to tell me that my sim card (the NEW ONE) was cloned or assigned to another number , having had to call them back again having them tell me that the sim swap was cancelled and that i need to go to the shop again, on MY TIME, and PAY FOR ANOTHER SIM CARD because they cant find the problem on their side!!! this is absolutely disgusting and deplorable service and i am the one battling to come right with this company!!! They are doing absolutely nothing to help me of rectify this situation! Having been a customer of Vodacom for more than 12 yrs personally and in a business aspect, i am seriously thinking about moving my contract and all business to another company!!!!!
