Poor treatment

I emailed First for women saying that they should contact me because I needed to change my bank details, i specifically told them to phone me at exactly 1pm, the reason is because that is literally the only time i have access to my phone. on three occasions they tried to phone me back, but it wasnt at 1pm because like i told them i only have access to my phone at exactly 1pm. so the people email me back and ask me for the details they need to change my bank details. but i tell them they should have called me because anything can be a **** on email these days. the people email me back with a very bad email telling me that they did try to contact me on three days and gave me the dates. i emailed back and said but i said at 1pm only they return my email again with another bad email saying that they cant help me when i ask (1pm) because of their call load...Really? This is not the first time they have manhandled me because i am a paying customer and i pay a lot. in my personal opinion outsurance is looking a lot more promising
