worse accounts service

<p> Ive had an account at lewis stores for m ore than two years now and I have been making EFT payment s for more than a year. But now all of a sudden, a pament made by me in Dec 2016 is not reflecting on the system , my balance is not updated but there is already interest on this account, people that I inquire with are telling me that I used an incorrect account number... for an account I have been paying via eft foe more than a year. The debtors lady at Stellenbosch is telling me that this quiry has to go through IT and she doesnt know when this paymwent will go through... Its been three weeks now, there is interest on this account. This is obv affecting my credit record. </p>
