Peach payments have zero interest in signing up new customers

Peach Payments seems to be completely disinterested in getting my business signed up to use their services. I've reached out many times via email and telephonically, moving through different levels of management, with little to no response back. It appears my high volume business is clearly not wanted or needed. I have found the service I am after with Payfast, who although more expensive deliver on their services, and I highly recommend them after a 5 star painless sign up, onboarding and integration. Peach payments, your attitude towards potential clients is absolutely disgusting.
