Terrible service, awaiting one week for my reimbur*****t

On the 10th of July 2023 i purchased a windscreen for my vw polo 2017. On the 11th i had my mother to call and check if all is well only to get the news that my windscreen had not passed quality check therefore i wouldn't be getting it. Why that wasn't communicated to me is a question. On the 12th we asked for a reimbur*****t so the sales person (desigan) said we had to fill out a reimbur*****t form. So we did and sent it through. We didn't get an acknowledgement of him receiving it. Later that day an email was sent asking for acknowledgment. It was only rep**** to the next day. My mother had sent another email asking about the progress and still no acknowledgment. I've been waiting for my money to be put back into my account from last week and it's currently the 19th of July. This lack of service has resulted in my missing my chalets in which i had booked for the weekend away R4800 lost due to me not being able to drive my car. Further more i spent close to R100 in airtime contacting vw regarding this matter and 90% of the time was told they would take a message and get back to me, which they never did. I've had to choice but to put an aftermarket windscreen which we all know does not fit 100% leaving my car looking like a complete mess another R1750 wasted there. I am truly disgusted with the service from such a big company like vw. I will never do business with you guys or even recommend yourl to anyone. For the 100th time, please treat this as an urgent matter and have my money transfered into my account asap!
