Miscommunication

I upgraded my phone and received it on 10/3/2015. It has n micro sim and mtn didn't want to do a simswop on the telephone. I went to the caledon branch and they told me to contact Summer Mobile which I Did. They then told me I can go to a mtn branch where they will help me, but non of the mtn shops I went to could help me. I cancelled this contract and told them to come and collect the phone, but after many phone calls and emails no one has showed up. Now they charged me R1040 and they have blocked my other phone nr. I'm terribly dissapointed because I've been with mtn for many years. I don't have a mtn shop where I live. So all I want is for someone to come and get the phone!!!!
