Change of phone number and unavailable service for +-2 months

I had my telephone number for more than 10 yrs, due to unwanted calls I asked to change my number in July 2017. I was given a new number. Since Sept 2017 when I paid my rental and ad airtime on my phone it was out of order and a voice telling me I must recharge airtime. I have not even use the phone due to me not having any service. I in the meantime discovered my old number has been given to some one else and my new nr still not working. The last 2 days people called on my phone asking for a business with a complete different number. All people concern specially our security has been informed of my new number. I received sms's from Telkom since 20 September they they are working on the fault. It is 11 sms's further and yet no phone working. This is the worst service I have had since I had a phone which could be for over 40 years. Telkom please wake up we need a phone that work, that is why we have it in the first place.

I had to pay to have my number change it is not as if I got it free. I assume that this faulty numbers got all my data that I have loaded. I also pay for my rental and wonder if you can start giving refunds on rentals for fault phones.
