Quote you 1 Price, Invoice you another

What terrible service we received from these Suppliers.<br> Quoted R495 call out, with a lock R195-R295.<br> Call out fee had to be paid before they go to property.<br> Thereafter I received a R470 invoice.<br> <br> When I tried to query this, I get such a rude, unprofessional lady telling me I'm wrong and they are not *******. (not sure where that comes from).<br> Thereafter my husband tried to query it and the phone was handed to Chris. He threatened to come to our house and sort out the problem man-to-man. (OMW).<br> <br> All because we queried an invoice that is incorrect!
