Unsatisfied service by DSTV insurance

I have a DSTV insurance and submitted a claim on the 3rd October in Vincent Multichoice offices in East London for my two decoders, I requested the lady to update my number on their sysytem as I have changed numbers. After two weeks of not getting any correspondence I called and was then informed that there is a delay in distributing the decoders, I then again requested my number be changed to the current one that I am using now. After another week I then wrote them an e-mail complaining of their poor service it was only then I was sent a tracking number, when tacking the number my decoders were sent to the Northen Cape where in the e-mail I did specify my address being in the Eastern Cape. I called them again this morning to make a follow up am told I was sent an Incorrect tracking number and that the delivery people called me on my old number and because they did not get in touch with me the parcel was sent back to the warehouse and I must again wait another 3-5 working days. Very poor and unprofessional service and lack of transparency and I am sure I will cancelling the insurance as it is useless, rather I go and buy.
