Not prepared to help a longstanding customer

My iPad fell and broke. I am insured with A&G because it is cheaper, they advised me to send the iPad to any repair centre to get a qoutation for repairs and if repairing mu iPad is even feasable. First, they sent it back to us in Groblersdal because they do not have the IEMI number while it it takes about 3 taps on the iPad and voila, the IEMI number is there! The local Vodacom shop sent the iPad back to Vodacare and they, in turn sent it back AGAIN stating that they will not help me since I am not insured with Vodacom. I have been a Vodacom customer, prepaid first and now on contract, and THIS is the treatment I get? I have a right to insure where I want to, the law gives me that right. Your company is not prepared to help me even though A&G would pay Vodacom for any repairs. All I need is a letter to send to them so a decision can be made as what to do. I am going to go through the consumer law to see what steps I can take against Vodacom.
