Suppose that you are talking to your friends about some of the customer reviews regarding their online shopping experiences. This is what you would say to them.
(ex) I have just read some customer reviews regarding their online shopping experiences with ABC Store. They are complaining about a high import duty they need to pay when they receive their orders.
Some of my non-native English speaking friends think my use of the mixed present tenses is okay because it carries a sense that the customers' complaints are ongoing. However, others think I should use the past tense.
I think I can use different present tenses in this context. Please give me your opinion.
