Their service is appalling

Their service is appalling. Their call center agents are rude. They call you 15 times a day and no one makes notes on the system. They don’t stick to payment arrangements and they just do whatever they want. The people that man the call center are rude, short and unhelpful. I don’t understand why there is a call center if the people working it can’t assist with anything. You have to wait for their systems if you need to be refunded for an amount that 100% is overcharged. It’s been a headache from start to finish.
