Bad after-sales service

We bought an RCT Megapower 3-4 months ago and after 2 months it had issues. We brought it back and had to wait 21 working days for repairs. When picking up, we were assured it had a brand new battery.

It lasted 1 day and battery already faulty. We were told by the branch to contact head office to ask for a refund or replacement. However, head office policy is to "send it back to supplier for repairs or credit". So we are without a back up during load shedding again for 21 working days. When asking if we can not get a replacement, we were told this is not policy. When asked if we can get a credit from the supplier, we were told “you cannot demand that as a customer”. This was all from head office.
