Discovery Shocking service

Vehicle was involved in an accident last year June and taken to Nu Wagon for repairs. We then picked up a noise on the front right and took Hyundai i20 to the dealer who stated the bearing needed to be replaced. I thought this to be strange as this was one of the parts listed for repairs and according to work had in fact been replaced. Discovery was called and hire car was arranged but nothing else done, after numerous phone calls attempting to resolve as limited days on hire car finally flipped my lid and they paid out for repairs. Bearing was replaced and we took it for wheel alignment but they could not do it as they found more issues: 1. Front right shock mounting damaged 2. front right cv joint boot dry (no grease) 3. Gear selector cable secured with cable ties 4. Back right bearing damaged Once again trying to get through to someone to assist and having to explain the whole story over and over again with no solution or assistance. After a few days get hold of Jathin (team leader) who promised someone from Net Asses within 4 hrs. 4 hrs pass and no call received. Following day I called Net Asses and they said they have not been requested by Discovery to call. I call Discovery again and ask what is going on after I have had to explain the whole story again. Again I am promised that someone will call, I wait.............. The next day I am contacted by Net Asses who were actually rather good, arrangements made to meet at a different repair company as I do not trust Nu Wagon at all, I met with Gert and the vehicle was hoisted and we went through all the issues which was confirmed as a problem as well as additional faults found and was also advised that vehicle is not safe to drive. I call Discovery and told them that I need another hire vehicle, was told to go to Monument Avis and call when I was there. Gert (Net asses) advised that he will send his findings to Richard who will compile the report and send to Discovery (To date they, Discovery, claim they have not received it but I have been misled before so not sure. Anyway, I go through to Avis who say they have received no reservation so I call Discovery again and they talk to the lady from Avis who informs them of the procedure, needless to say I arrange someone to fetch me as I cannot stand around like a lost ****. Here I sit with a hire car which I am told is coming off my 30 car hire benefit and after speaking to numerous people again I have yet to receive feedback over a week later. I as a customer have to phone every day, explain the story every day, ask to speak to a manager every day only to be told NOTHING, the hire car is due back this week and here I sit. THEY approved the vehicle to be repaired by Nu Wagon ****** not me, so why is it that I have to beg & plead for assistance with this to just get resolved, surely I am not the only one who has been ****med by Nu Wagon's ********** repairs who's license should be cancelled with immediate effect. On another note, I am still owed monies for my drive cash back from October & December of last year and January this year and every month I have to call them to ask for the monies to be paid and promise after promise I am told next month, next month, next month. I am seriously contemplating on cancelling ALL my policies with them as this is utterly and downright disgusting
