Poor Service

i sent my car for service on the 15/10/2015 as it had electrical problem i also wanted it to have Major service and wheel alignment, i was told the person who does electrical problem is at Pretoria he will be back on Monday, they stated to fix the car from Monday and i paid R10385.86 for the whole thing but when i got the car on the 23/10/2015 it was making funny sounds and it was overheating i though maybe since the service it will get better but it got worse as the over heating never stopped the car ended up breaking down on the 28/10/2015 as it was over heating the fan belt exploded while driving i had to tow the car back home. i paid lot of money to have a car in good condition but they made my situation worse, i will never recommend anyone to use their service as it it poor, the review mirror was broken also as it kept falling off when i drive. i need the car fixed or paid back my money.
