Vodacom disrespectful Service Horrible

I'm here because I'm having big headache with Vodacom and loosing a lots of clients because of them. I was at Vodacom Shop in Waterfront on the 26 of April 2018 and I blacklist my Iphone7 128G. They gave me ITC number from a Huawei Ascent. My insurance told me on the next day that wasn't the EMEI from my Iphone. I went back there on Monday the 30th to change they change the EMEI to my Iphone, but they gave me the same ITC number that is ****114 and I send it to my insurance. And once again they told me that the ITC still take them to Huawei. I went into Vodacom again, they again try to blacklist my phone once again, we did not receive the ITC number again. They told me the system wasn't working and that I need fill in a form for Blacklisting and they should contact me in 48hours they gave me a reference number ********** . But I haven't heard from them until today. In the mean time I keep trying to call them and talk to them and they keep saying that I have to wait. I keep going back to vodacom in Waterfront and they also keep trying to call them but no answer. I was in Vodacom in waterfront again yesterday 19 May and he try to contact Vodacom service, but they kept changing him from line to line and in the end here said they wasnt working because was Saturday afternoon, what about my work and the clients that I'm loosing. Its not fair, I lost a lot of client, because I still don't have my ITC number, and I cant afford to buy a new Iphone now. Every month I pay my bill with vodacom go between R 2500 and R3000 , and now I have to pay for a month for something that I"m not using it for a month. I send them an email for ********** also no answer. We try more them 10 times for the ITC number and still nothing even send the form to them. That is unaseptable and unprofessional from them. And I bougth my Iphone7 128G from Vodacom in Cape Quarter. Please I need help I don't know what to do anymore, I can't keep loosing client. Anyone Please help me.
