Lewis Store Mafikeng

The Lewis store in Mafikeng has been threatening to repossess furniture I bought in December, the store was supposed to debit my bank account on the 1st of January which they didn't, I assumed they would debit on the 15th but yet again they did not, the next communication was them going to my place of residence and threatening to repossess my furniture... If this is how they conduct business then this will be the first and last purchase I ever make from this store
