Conveniently cannot trace payment

Disgusting service received from this company I am convinced they don't want people to be debt free. I made a payment days ago using the link they provided on an email. Continued receiving disgusting emails from them. I then called to inform them that I made a payment only to be told they didn't receive it as yet. I paid using the link on the email they sent to me. I then asked for banikg. Details so I could do an Eft payment going forward as clearly it seems like the link is useless as it takes days to allocate payments apparently you cannot pay via Eft only the stupid link and debit order. They are horrible to deal with. You will be paying and nothing will happen they will just send you annoying emails. They want you to pay but when you pay they can't find your payment.Is this the company woolworths trusts....
