****ing terrible **** service

So i purchased a vehicle in march a VW polo, the previous owner had the vehicle serviced at Strand fitment centre in January, i drove the car for less than 2 months and the service light went on, VW-Barons refused to set the timing for this and i had to go all the way to strand from the heart of CPT, went there and i got a very arrogant attitude from the owner-manager boss whatever he is him and his guy supposedly reset the timing on the service light without showing myself and my hubby what they were doing, also this idiot did not have a mask on and he still coughed in the car, thats not the point though, its a month later and the service light is on AGAIN, i took the car to barons, paid to have them check if it actually needs something done, low and behold i was told the people who set the timing either caught on **** or did not service the car correctly. So this morning i phone a i tell the receptionist that the light is going on again so it wasnt set right and she literally has the nerve to tell me that there must be a problem, seriously? Please do not take your car for any service or motor work to be done rather go to a proper place i dont even think they are qualified to be doing servicing .
