Embarrassing moment with poor service

What an embarrassment moment with the poor service I had to experience 😞 so yesterday I was at Fashion Fusion at Maponya Mall looking forward taking out my lay-buy, so seeing that tht store is in partnership with Pay Just Now I wanted to use my Pay Just Now to take out my lay-buy bt wow the store manager/cashier not to sure wats her position told me I cannot use my Pay Just Now the 12 month option which they call it Pay Strecth, she told me I need to use the 3 months option so I want to find how can she tell me what option to use, next thing shes telling me I wont get the clothing they dont use the 12 months option that clearly makes no sense in hell to me I need this matter to be resolved hence I was so embarrassed infront of my kids this service was really uncalled for.... I called the Head office this morning regarding this query spoke to Layah and told me she will get back to me awaiting for the call till now
