Agent has *********** Customer Relations skills

Error 1: Upon requesting a quote via their website, Palesa called me back asking me if I would like an overnight delivery or next-day delivery before even providing me with the cost of each. Only after asking did Palesa advise that the overnight delivery was more expensive. Logically, as a customer, I need to know the cost of each before making a decision. The quote provided was also miscalculated and I (the customer) had to point this out. If I didn't point it out, I would have paid extra?! Error 2: When payment was requested, Palesa first omitted to send banking details for me to effect payment. Thereafter, she omitted to send the Account Holder's name and Reference. This is frustrating for a customer who needs things to be done efficiently (which sums up all customers)! Error 3: I asked Palesa to have the package collected from my residential address at 6pm (after hours). Palesa never mentioned in advance that there would be an after-hours charge. Palesa called me the next morning, advising of the after-hours charge and expecting me to pay it (after the fact), which I obviously rejected since I was not advised of it. How can I be expected to be held liable for her error??
