Very bad service.

I bought a ProGlo Dual Cure Lamp on the 5/6/2018 at Planet Nails Distribution, Monument Road, Johannesburg. 5 of the lights went dead in July and I took it to the store, where they send it back. I waited 4 weeks, not the 1 week that they said it would take. They exchanged the lamp on the 16/8/2018 and I only got it back end of August. The 14/11/2018 when I wanted to use the lamp, the lights flickered and went out. I tried it again, it flickered once and went dead. I took it back to the store, where I asked for my money back. They said they can't give me my money back, they can only send it to Head Office to be repaired / exchanged on the 22/11/2018. They said it would be back the 29/11/2018 but they never called me. I emailed the Head Office, to ask for some feedback on the lamp. They said they credited the lamp and the store will assist me further. Today, 3/12/2018, I went to the store after not hearing from them. The assistant told me that if I want the cash refund they could only give me R237 back or I can take another brand of lamp. I told her I don't want anything from Planet Nails ever again I just want the R799 back what I paid for the lamp. After she call the manager that wasn't at the store and a big argument, they only gave me R530 back. I think it is really bad client service and I will never buy products from Planet Nails or recommend Planet Nails to anyone ever again, if this is the way they do business.
