13.4 Notwithstanding / regardless of the above figures, any rescission of the contract will (oblige the contractor) entitle the contracted party/service provider to arefund in the form of an advance payment where applicable.

Of course it's only a matter of time before a certain person drops by with his crass, spurious and convoluted observations in barely intelligible English in his perennial attempt to muddy the waters and because he can't resist the opportunity to p@ss on someone else's parade, but my understanding is clearly expressed in idiomatic English of the right register. Also I believe it is better to keep to the original format as I have done in the answer box, rather than turn the phrase round on its head as three answerers to your previous question attempted to do(spurred on of course by the totally unnecessary and unwanted intervention of the above -named person!) Hope it helps!
