Phone Lost,No help

after handing in 2 phones at afrihost walkin centre was only told to make sure he puts the correct address at which the phones should be returned...After waiting a while for the phones to be repaired I started getting annoyed, but stayed away from asking questions/phoning....a month later only one phone gets returned albeit unfixed, stating that the phone had been tampered with(who tries to fix a phone still under warranty?????)....so I decide to contact zest in order to find out what happened to my phone, I was first accused of *****ing from what I understood and had to get my brothers(Afrihost account holder) ID number by the first consultant....The second consultant after giving proof of account holder asked for thr serial number on the phone that got returned, it would apparently help them track the MISSING phone....thereafter I sent an email and this is the response I received <br> <br> I would really like to help you but there are a few problems.<br> <br> You are e-mailing from an account that is not on the system, and the cellphone number does not match the ID number on the system.<br> <br> The phone is with Zest at which point we have no control over what happens after...Havent heard since
