Very poor customer service

I ordered two bedside tables on the 20th Nov. We had to build it ourselves, one unit was okay and unfortunately the second unit had a part which was smaller. I logged a return and exhange to get another unit. They sent a driver to collect the unit, but he only collected just the part which was smaller. Long story short, afterwards i had to return the rest of the unit to one of the pick up points. The rest of the unit was booked in the warehouse so i was told, and suddenly on the app my return is cancelled. What is frustrating about this whole process is that nobody gives you feedback on what is going on and you speak with different agents everyday. They do not reply to the emails and you have to call each time, only to wait some more to understand what is going on. This is definitely going to be my last time I buy anything from superbalist. My return/exchange issue is still pending its very frustrating that one thing is taking a whole month to get resolved
