Double Billing, bad customer service

Their customer service on the finance side really disappoints. I paid double end of July, they contended me and asked to do a manual payment but they proceeded to debit me as well after the manual payment.

I logged a ticket and it took them 2 months to get back to me. The first interaction they assured me I will not be charged end of September, they again debited me the amount.

They called me 2nd October and a lady named Elsie assured me its sorted out and I will get an email from het with details. I received no email from Elsie and I was debited again that evening. I cant imagine the chaos in their finance department.
