USELESS & PATHETHIC CUSTOMER SERVICE FROM FNB

my credit card machine is not accepting cards, from yesterday. this morning i have called in 4 times and have spoken to approx 5 people to sort. However they not sure why it is not working. i have been on my cellphone prepaid for over hour and half AND WAS RUNNING OUT OF AIRTIME. i asked that they call back, they said they cannot call out. USELESS SERVICE, PATHETHIC SERVICE. the consultant said he will get another person to call back from another department, straight away. an hour has passed and nobody has called. i just called in again and they said they will get somebody to call back. so far no call. to order and receive the terminal was also a major headache and a wait and fight for 2 weeks to get, after the date they they were to deliver. also had to do a hellopeter to get that one sorted out. seems as though your whole department is just useless and its very frustrating for us customers. i need my machine to operate, as currently loosing sales and income. WHEN WILL I GET THIS SORTED OR WILL IT TAKE ENDLESS DAYS OF CALLING IN AND GETTING NEW REFERENCE NUMBERS. PERHAPS ITS TIME THAT I CHANGE TO A BETTER BANK.
