The worst service provider

Two weeks ago my car towed for repairs and i was never contacted nor did i receive any sort of notification from their side. It took them more than 7 days to get an assessor to asses my car and now that everything is done, they still have not contacted me.

i contacted them this morning and only to be advised that they want invoices from all the dealers that attended to servicing my car. copies of my service book are not enough proof. i am advised to call all the dealers and request invoices as from 2015 which is the year i bought my vehicle and after receipt of the said Invoices, i will be advised if they accept my claim or not.
