Lost Phone at Vodacom Repairs

Almost 2 moths ago I sent my Samsung S3 mini for repairs at Vodacom Repairs at Canal Walk. I received a call to fetch my phone but when I went to the store it was lost. The consultant then said that he will forward an email to a Miss Lynne who deals with Vodacom insured devices. It has been 3 weeks and I received no call. I decided to phone them this morning and it seems my problem has not been addressed. As if that is not worse insurance said that I must pay R814 in order for me to receive another device of which they don't have on stock because it has been discontinued. I then have to run around looking for this S4 mini at whichever store that has it on stock but before I can do that I need to get the lost S3mini which they said is beyond repairs which I need to give in with the R814 in order for me to get a replacement phone. I accepted my fate but now I cannot get the new device without the old one. In the process I requested a loan phone, the first 1 they loaned me had a wrong charger and the second one is problematic as I cannot read my sms's. I have been patient enough with this company I want to cancel the contract and insurance with Vodacom and get my non-reparable device.
