Lewis Store Inquiry

My account was not debited in December and they held me accountable for that by adding interest for the unpaid transaction which was not even my fault. I called in to enquire about the account to find out that I was not even getting a difference with each installment paid towards the outstanding balance. I was told by the accounts manager that they will credit 6 months and i will be sent a statement which has not been done. I called in today and spoke to Sibonise in Accounts department who advised i will not be sent a statement as they are sending me a link for the monthly invoices, transferred call to another department which returned the call again to accounts and spoke to Sesethu who advised the statement will be sent. I'm appalled by the level of incompetency the store has shown as it seems each agent is working on their own discretion and they mostly have attitude towards their customers. There was an entire month where i was calling and was advised they having issues with network for an entire month which did not make sense. If no response is obtained , i will have to raise the matter with ombudsman as i have been pleading with Lewis to do right by my account as this has an overall impact on my ITC profile ..
