Poor service delivery

I took my car to be repaired at Peugeot PTN because I have a maintainance plan with 360 plus liquid capital Peugeot had to claim to them but gues what no one wanted to be responsible the people who are working at authorization department kept Peugeot waiting for approval, and it happened for two days so because I needed my car badly I had to pay R7152 from my pocket. The third day it was on the 18 March I got hold of Thabo who said I mus fax proof of payment service book and ma ID, I did fax but there was no response, I kept calling them then I got hold of Ronel, she said I will get my refund after 21 days till today these people are fooling around with me, now I'm asking myself is this the kind of service I will get from now onwards and in SA do we still have such company who are doing a day ******* with their clients? And worse none of them wants to give me the managers numbers they told me it's not allowed what kind of an organization is that, people take it from me I have been warned before I joined them cause somebody once told me their service s***** but I had to prove it my self I'm rating them ZERO in service delivery
