Very bad service delivery!!!

On 26th september i handed in my cellphone device for repair and received my ref number.Since then finrite never came back to me regarding this matter,the repair centre sent my device back to telkom whereby finrite never came back to them as well, when they sent a quote to them, for when they wanted to fix the device.I went back to telkom, the device was send back for repairs and i got a new ref number and the whole process repeated itself again and in the mean time,i spoke to numerous people at finrite,who informed me,they will look into my case and ive waited.I went back to telkom and received my 3rd ref number for my device and the same time i phoned finrite to inform them, the situation and some dude told me they under new administration and that i myself must fill in a claim sheet,whereby nobody informed me of such doings and i was under the impression telkom already did that as for they are my service provider and they confirmed with me,i dnt need to do that, they'll sort it out! I am still waiting on telkom and finrite to come back to me and as a customer i feel this is the worsed service i got from any business in my life!!! Is it so difficult to to repair a device and ive seen a few unsatisfied people complaining about finrite and something must be done and to pay for something u dont use it doesnt work for me and insurance that dissapoints you in such a way!is there a office i can walk in and give them a piece of my mind?
