Customer service on claims sucks big time

I have been waiting for my cellphone for more than a month now. I had to take out a new contract because Finrite does not provide you with a loan phone and i need my cellphone for work. On the 19th of June they gave me the excess amount after having the phone for almost 2 weeks basically (claim submitted on the 10th of June, repairers received the phone on the 11th) . I paid 750 before I received the sms as thats what my contract said, the sms then said the excess is R809. I paid the difference on the 19th. On the 2nd of July I received a sms to say that my device has been authorised and will be repaired. After this I called Finrite to tell them to deliver my phone back to the shop that I dropped it at. Then I received a sms on the 10th of July to say that the repair is complete and that the courier will contact me. Courier never contacted me, I called Finrite almost every day, not getting through. I then went to the Telkom store (a week later) where I dropped the phone off and they told me they havent received my device. I then called Finrite again and they dont answer. I then called finrite on the 27th of July cause now its been 17 days since I was told my phone is on its way back, they tell me Oh sorry there was a mix up and we sent your phone to the wrong store. They then said they would call me today the 29th of July to tell me where exactly my phone is and when I will receive it and still I received no call today. This is so frustrating and unprofessional. I have been paying for a contract for two months for a cellphone I cant use. Please just give my phone I have been paying my insurance for almost two years without missing a payment and this is not the service I expected
