Wesbank Mahindra Finance complaints resolution doesn't reply

I bought a Mahindra Scorpio-N last year, the car has gone back to the delearship 14+ time in the first couple months of this year. I lodged two complaints - *** // CRSE0498 the first was sorted. The second was lodged on the second of May - CRSE0498 - [External Email] CRSE3591 - I received an email with the 5 days to confirm and follow up on the complaint - I had to follow up on the 28 as I received no feedback. The case was then escalated to Lizelle Wellsted who followed up. The case was closed with no resolution, and no follow up from Wesbank. The car is going back again for another steering issue and I sent an email on the 2nd July asking for more information on whether I should lodge a new case or continue on the same case? Still no reply.
