Horrible service , the client has to continuously follow after them

The worse experience ever, they have already deducted money on from my account about a week ago , yet I had to follow up with them and ask them when they will install the unit on my car, to my great shock they received the enquiry from budget but decided to ignore it, cool since I was already on the line they set up my account and promised to get in touch , till this day nobody has gotten in touch , I called again today , the lady hung up whilst I was talking to her yet should anything happy to my vehicle they will not take any accountability, they have my money , but the services that I have paid for are not rendered , I keep following up after yourl like a little puppy, what did you take my money for ?
